The 17 most common MMA injuries: bruising, lacerations, fractures, sprains and strains, concussions and knee damage.
Striking and grappling both take their toll, so dislocations, eye injuries, a ruptured eardrum, rib and neck trouble and facial fractures round out the list, each with its causes and warning signs.
Injury Rates and Numbers
The figures below come from injury surveillance data and peer reviewed studies. Each row names the population it was measured in, because rates from elite athletes and from recreational players are not comparable.

Bruising (Contusions)
A contusion is bleeding inside a muscle or in the fat layer under the skin after a blunt impact, without the skin being broken. In MMA they come from checked low kicks against the outer thigh and shin, from body shots into the abdominal wall, and from knees and elbows landing on the forearms you block with. The muscle fibers and small vessels are crushed against the bone underneath, which is why contusions over the thigh and shin hurt far more than the visible mark suggests.
Symptoms
- A dull, deep ache that gets worse when you tense the muscle.
- Discoloration that appears over hours and travels downward with gravity.
- The area feels firm and warm to the touch.
- You lose some range of motion because stretching the bruised muscle hurts.
- Kicking, checking or gripping on that side feels weak rather than painful at first.
How serious it is: Most contusions are superficial and settle within days. The concerning form is a deep thigh contusion where the muscle stays tight, the knee cannot bend past ninety degrees, and pain keeps building instead of easing.
Typical time out: A few days to two weeks for a simple bruise. A deep quadriceps contusion that limits knee bend can take three to six weeks, because the limiting factor is regaining flexion, not the pain.
See a doctor if: Get checked if pain keeps rising after the first day, the limb feels tight, numb or cold, or the muscle stays visibly swollen and hard.
What helps
- Short cooling in the first hours if it helps the pain, then move on to gentle motion.
- Keep the joint above and below moving early within a pain limit, since immobility is what leaves you stiff.
- For a thigh contusion, work on regaining knee flexion daily rather than waiting for the color to fade.
- Pad the spot and change what you drill: hold pads instead of taking kicks for a week.
- Repeated bruising over the same bone, especially the shin, is a signal to reduce hard sparring volume rather than to toughen through it.
Lacerations
A laceration is a split in the skin, usually where skin lies directly over bone with almost no padding: the eyebrow ridge, the cheekbone, the bridge of the nose, the scalp. Elbows and accidental head clashes are the usual cause, because a hard edge driven into thin skin over a bony ridge bursts it from the inside. Facial lacerations are the single most common injury recorded in professional MMA competition.
Symptoms
- A sudden warm, wet feeling rather than sharp pain.
- Bleeding that is heavy and immediate, especially around the eyebrow and scalp.
- Blood running into the eye and blurring vision on that side.
- The edges of the cut gape when you raise your eyebrows or open your mouth.
- Corner mates stopping you between rounds to work on the same spot.
How serious it is: A shallow cut that stays closed on its own is minor. Depth, gaping edges, a cut across the eyelid margin or lip border, and any cut that will not stop bleeding under pressure all raise it to a wound that needs closing by a professional.
Typical time out: Skin closes in one to two weeks, and stitches usually come out in five to seven days on the face. Full strength of the scar takes six weeks or more, which is why most commissions impose a suspension of thirty to sixty days before you can be struck there again.
See a doctor if: Go in the same day for any cut that gapes, that crosses an eyelid or lip border, that still bleeds after ten minutes of firm pressure, or that leaves numbness in the skin nearby.
What helps
- Firm, continuous direct pressure with a clean cloth, not repeated peeking at the wound.
- Cleaning with water or saline once bleeding is controlled, then a simple dressing.
- Professional closure within a few hours where it is deep or gaping, since late closure scars worse and infects more.
- Keep the healing scar out of sunlight and off the mat, and do not resume sparring just because it looks closed.
- If the same eyebrow opens repeatedly, it is scar tissue splitting; a specialist revision plus a change in defensive habits matters more than tougher dressings.
Fractures
A fracture is a break in the continuity of bone, from a hairline crack to a displaced break with fragments out of line. In MMA the pattern is specific: the small bones of the hand from striking, the nose and orbital rim from punches and elbows, the ribs from body kicks and knees, and the forearm bones from blocking. The bone fails because force arrives faster than the surrounding muscle can absorb it.
Symptoms
- Pain that is sharply localized to one point rather than spread over an area.
- Immediate loss of function: you cannot make a fist, take a breath in, or bear weight.
- Swelling that comes on within minutes rather than hours.
- A visible bend, step or shortening of the limb.
- A grinding or clicking feeling when the part is moved.
How serious it is: Undisplaced hairline fractures often heal in a cast or brace. Displaced fractures, fractures into a joint surface, and open fractures where bone has broken the skin are surgical problems and carry the risk of lasting stiffness.
Typical time out: Six to twelve weeks for bone to unite, and three to six months before full contact, depending on which bone and whether it was fixed with plates or screws. Hand and rib fractures sit at the short end, forearm and displaced joint fractures at the long end.
See a doctor if: Any visible deformity, bone through the skin, numbness or a cold pale hand or foot below the injury is an emergency, not something to sleep on.
What helps
- Splint the limb as it lies and get imaging; do not test it by trying to use it.
- Accurate diagnosis first, since several MMA fractures look like sprains for the first two days, especially the scaphoid in the wrist.
- Load the rest of the body throughout the immobilized period so you are not rebuilding everything at once.
- Structured rehab for the neighboring joints as soon as the cast or brace comes off, because stiffness costs more time than the fracture did.
- Clearance by imaging and by function, not by the calendar alone, before you return to striking.
Sprains and Strains
A sprain is a stretch or tear of a ligament, the tissue connecting bone to bone across a joint. A strain is the same damage in a muscle or its tendon. MMA loads both at once: ligaments give way when a joint is levered past its range in a submission or a takedown scramble, and muscles tear when they are contracting hard while being lengthened, as in a checked kick or a defended shot.
Symptoms
- A pop or tearing sensation at the moment of injury.
- Pain when you tense the muscle yourself, in a strain, or when the joint is pushed sideways, in a sprain.
- Swelling within the first hours and bruising a day or two later.
- A feeling that the joint is loose or that the muscle will not fire fully.
- Stiffness that is worst after sitting still.
How serious it is: Both are graded 1 to 3: grade 1 is a stretch with intact tissue, grade 2 a partial tear with some laxity or weakness, grade 3 a complete rupture with obvious instability or loss of function.
Typical time out: Two to six weeks for a grade 1, six to twelve weeks for a grade 2, and three months or more for a grade 3 or a repair. The spread is wide because a grade 2 in a small ankle ligament and a grade 2 in a hamstring behave very differently.
See a doctor if: See someone if the joint gives way under you, if you cannot put weight on it at all, or if a muscle shows a visible gap or a bunched lump.
What helps
- Early movement within a pain limit; protected loading beats waiting for pain to vanish.
- Progressive strengthening of the injured tissue itself, ending with fast and eccentric work before you return.
- Rebuild balance and joint position sense, which is what actually prevents the repeat sprain.
- Return by criteria: full range, near-equal strength side to side, and sport-specific movement without compensation.
- Imaging only if function does not return as expected or if instability suggests a complete tear.
Concussions
A concussion is a functional injury to the brain from a blow or from rapid rotation of the head, not a bruise you can see on a scan. In MMA it comes from hooks and elbows that rotate the head, from knees in the clinch, and from the head striking the canvas after a knockdown. Ringside data show concussions are far more frequent in the fighter who loses the bout than in the winner.
Symptoms
- Headache and a pressure feeling in the head.
- Feeling dazed, slowed down or as if you are behind a fog.
- Dizziness, nausea, or sensitivity to light and noise.
- Trouble remembering the round or the minutes around the blow.
- Sleep that is broken, and irritability or low mood in the days after.
How serious it is: There is no useful mild or severe grading applied on the day; any suspected concussion is removed from the session or bout. What varies is recovery: most clear within two to four weeks, while a minority have symptoms that persist longer, and repeated exposure before recovery is the real danger.
Typical time out: Symptom recovery usually takes one to four weeks, but return to sparring is governed by medical clearance and by commission suspensions that commonly run thirty to ninety days or longer after a knockout. A second concussion before the first has cleared extends everything.
See a doctor if: Emergency care for any loss of consciousness lasting more than a moment, a seizure, repeated vomiting, worsening headache, one pupil larger than the other, weakness on one side, or confusion that deepens.
What helps
- Leave the session immediately; there is no version of continuing that helps.
- One to two days of relative rest, then light aerobic activity below the symptom threshold, which now beats sitting in a dark room for a week.
- A stepwise return through non-contact drilling before any contact, with a doctor signing off.
- Targeted treatment if specific symptoms persist: vestibular work for dizziness, neck rehab for headache from the cervical spine, vision therapy for focusing problems.
- Honest tracking of your career total, because repeated concussion is the exposure that matters, not any single one.
Knee Injuries
The knee is held by four ligaments and cushioned by two menisci, and MMA loads all of them in unusual directions. Takedown scrambles twist a planted foot under a turning body, which is the classic mechanism for the anterior cruciate ligament and the meniscus. Heel hooks and knee bars rotate or hyperextend the joint directly, and a leg kick caught on the outside of the knee stresses the medial collateral ligament.
Symptoms
- A pop at the moment of injury, followed by swelling within a few hours.
- The knee giving way when you turn or change direction.
- Locking or catching that stops the knee straightening fully.
- Pain along one side of the joint line rather than all over.
- Difficulty kneeling, squatting deeply or shooting a takedown.
How serious it is: Ligament damage is graded 1 to 3, with grade 3 a complete tear. A medial collateral injury usually heals without surgery even at grade 3, while a torn anterior cruciate and a locked, torn meniscus usually do not.
Typical time out: Two to six weeks for a grade 1 sprain, six to twelve weeks for a grade 2 collateral injury, and nine to twelve months to return to full contact after cruciate ligament reconstruction. Meniscus surgery ranges from six weeks after trimming to four months or more after a repair.
See a doctor if: Get it examined if the knee swells within an hour, will not straighten, or gives way under normal walking.
What helps
- Early assessment of what is actually torn, since the treatment paths differ completely.
- Restore full extension first; a knee that will not straighten never rehabilitates well.
- Progressive quadriceps and hamstring strengthening, then hopping, cutting and landing work before mat return.
- Hinged bracing for collateral ligament injuries during the return phase.
- Rule changes in your own training: cap heel hook exposure and tap early on rotational leg locks, because that is the mechanism you control.
Dislocations
A dislocation is a joint surface driven completely out of its socket, tearing the capsule and often the ligaments and labrum around it. In MMA the shoulder goes out when the arm is forced back and outward, in an armbar or in a failed underhook, the fingers go out in the gi or in grip fights, and the elbow can dislocate when hyperextension continues past the ligament’s limit in a locked armbar.
Symptoms
- An obvious change in the shape of the joint.
- Severe pain and a total unwillingness to move the limb.
- The arm held in one fixed position, often away from the body.
- Numbness or pins and needles below the joint.
- A sense that the joint slipped and did not go back.
How serious it is: A first-time dislocation that reduces cleanly and has no fracture is the mild end. Repeat dislocations, damage to the labrum or bony rim, and any nerve involvement mark the severe end, and each further episode makes the next one easier.
Typical time out: Six to twelve weeks for a first shoulder dislocation treated without surgery, and four to six months after stabilization surgery before full grappling. Finger dislocations that reduce well allow taped training in two to four weeks but stay swollen for months.
See a doctor if: Anything that stays out of place, or any numbness, weakness or absent pulse below the joint, goes to an emergency department now.
What helps
- Support the limb as it lies and let a professional reduce it, since a fracture may be sitting behind the dislocation.
- Imaging before and after reduction rather than relying on how it feels.
- Structured rehab of the rotator cuff and the shoulder blade muscles, which is what carries the joint once the capsule is stretched.
- For young fighters with a first shoulder dislocation, an early surgical opinion is reasonable, because the repeat rate without it is high.
- Tape and progressive grip loading for fingers rather than pulling straight back into hard grip fighting.
Overuse Injuries
Overuse injuries are failures of tendon, bone or cartilage under repetition, without a single moment of trauma. The tendon does not become inflamed so much as it becomes disorganized, which is why the word tendinopathy has replaced tendonitis. In MMA the usual sites are the patellar and Achilles tendons from repeated shooting and pushing off, the elbow tendons from grip fighting, and stress reactions in the shin from running and kicking volume.
Symptoms
- Pain that appears at the start of a session, eases as you warm up and returns worse afterward.
- Stiffness in the tendon in the first steps out of bed.
- A tender spot you can put one finger on.
- Pain creeping earlier into each session over weeks.
- Strength that fades in the specific movement, such as gripping or pushing off.
How serious it is: The mild form hurts only after training and settles overnight. It becomes serious when pain is present during the session, when it wakes you at night, or when a bone stress reaction is suspected, because that can progress to a stress fracture.
Typical time out: Rarely a clean break from training: expect six to twelve weeks of modified loading for a tendinopathy, and longer if it has been building for months. Bone stress injuries need four to eight weeks of genuine unloading before rebuilding.
See a doctor if: See a clinician if the pain is in the bone rather than the tendon, if it hurts at rest or at night, or if it has not moved in six weeks despite reduced load.
What helps
- Slow, heavy, progressive loading of the tendon, including eccentric work, which remodels the tissue rather than just calming it.
- Manage total load in writing: sessions per week, rounds, running volume, and change only one at a time.
- Address the technical cause, such as landing mechanics on kicks or grip habits that overload the forearm.
- Corticosteroid injection is not a first answer for tendinopathy: it can reduce pain briefly but outcomes tend to be worse in the longer term, so keep it as an exception.
- Imaging when a bone stress injury is suspected, since that changes the plan from loading to unloading.
Eye Injuries
The eye sits in a bony socket that protects it from most blunt force but not from fingers. Open-finger gloves mean an extended thumb or fingertip can reach the cornea, the clear surface layer, and scratch it. Heavier blunt impact can bruise the inside of the eye, bleed into the front chamber, or in the worst case pull the retina away from the back wall.
Symptoms
- A gritty feeling as if sand is in the eye, which is typical of a corneal scratch.
- Watering and an inability to keep the eye open in light.
- Blurred or double vision.
- Flashes of light or a shower of new floating specks.
- A dark curtain or shadow moving across part of your vision.
How serious it is: A corneal abrasion is painful but usually heals fully in a couple of days. Blood inside the front of the eye, a change in pupil shape, and any curtain or flashes suggest damage inside the eye and are sight-threatening.
Typical time out: Two to seven days for a simple corneal abrasion. Weeks to months and a formal ophthalmology clearance after bleeding inside the eye or a retinal problem, and some retinal injuries end contact sport participation.
See a doctor if: Flashes, new floaters, a shadow across the vision, blood visible in the front of the eye or any lasting change in vision means the same day to an eye specialist.
What helps
- Stop the session and do not rub the eye, which turns a scratch into a larger one.
- Rinse gently with clean water or saline only for a surface foreign body, and shield rather than pad the eye if you suspect deeper injury.
- Examination by an eye specialist for anything beyond a brief gritty feeling, since a retinal tear is silent until it is not.
- Ask for a dilated retinal exam as part of your regular fight medicals, because early tears are treatable.
- Insist on eye-gouge fouls being called in training; the habit of open, extended fingers is the modifiable cause.
Ruptured Eardrum
The eardrum is a thin membrane at the end of the ear canal. A flat, cupped hand or a glove landing squarely over the ear compresses the column of air in the canal, and that pressure spike bursts the membrane from the outside. A hard slap to the ear does this far more readily than a punch that lands on the side of the head.
Symptoms
- Sudden sharp ear pain that then eases quickly.
- Muffled hearing or a blocked feeling on that side.
- Ringing or buzzing in that ear.
- Clear or bloody fluid draining from the ear.
- Dizziness or a spinning sensation.
How serious it is: Most small perforations close by themselves. A large tear, one caused by an object entering the canal, or one with vertigo and marked hearing loss points to damage deeper in the middle or inner ear and needs specialist care.
Typical time out: Small perforations usually close in six to eight weeks, and you stay out of hard sparring and out of the water for that period. If it does not close and a graft is needed, add another two to three months.
See a doctor if: See a doctor promptly for any drainage, spinning dizziness, marked hearing loss or facial weakness after a blow to the ear.
What helps
- Keep the ear dry: no swimming, and shield it in the shower until it is confirmed healed.
- Do not put drops, water or cotton buds into the canal unless a doctor prescribed them.
- Avoid forceful nose blowing and pressure changes, which push air through the hole.
- Get a hearing test and a follow-up look at the drum rather than assuming it closed.
- Headgear with ear protection during sparring is the practical prevention, along with training partners who slap less.
Sprained Ankles
Most ankle sprains tear the ligaments on the outside of the joint, above all the anterior talofibular ligament, when the foot rolls inward under a loaded leg. In MMA this happens on a missed or checked kick, when a foot catches in the mat or cage fence, and in sprawls where the toes stay planted while the body turns. A high sprain, between the two shin bones, comes from the foot being twisted outward and behaves very differently.
Symptoms
- Pain and swelling on the outside of the ankle within an hour.
- Bruising that spreads into the foot over a day or two.
- Limping, or being unable to push off on that foot.
- A sense of the ankle rolling again on uneven ground.
- Pain higher up between the shin bones, which suggests a high ankle sprain.
How serious it is: Graded 1 to 3 by how much of the ligament is torn and how loose the joint is. Grade 1 is mildly painful with normal walking, grade 3 leaves the ankle unstable and swollen across the whole joint.
Typical time out: One to three weeks for a grade 1, three to six weeks for a grade 2, and eight to twelve weeks for a grade 3. A high ankle sprain runs longer than a comparable low one, often two to three months.
See a doctor if: Get imaging if you cannot take four steps on it, if there is bone tenderness on the back edge of either ankle bone, or if the foot looks out of line.
What helps
- Walk on it early within a pain limit, using a brace or tape for support rather than crutches for weeks.
- Balance and proprioception training, which is the single best evidence-backed way to cut the repeat sprain rate.
- Calf and peroneal strengthening, then hopping and cutting before mat return.
- Wear a brace or tape for the first months back, especially in stand-up rounds.
- If pain and instability persist past three months, get reassessed for a missed fracture or cartilage injury.
Shoulder Injuries (Rotator Cuff Tears, Shoulder Impingement)
The rotator cuff is four muscles whose tendons wrap the head of the humerus and hold it centered in a shallow socket. In MMA the cuff is loaded in the worst position repeatedly: arms overhead in a collar tie, arms forced backward in an armbar or kimura, and hard eccentric braking on every punch that misses. Impingement is the painful pinching of those tendons and the bursa under the bony arch when the shoulder blade does not rotate out of the way.
Symptoms
- Pain on the outside of the upper arm rather than deep in the joint.
- Trouble reaching overhead or behind your back.
- Pain when lying on that shoulder at night.
- Weakness when lifting the arm out to the side or rotating outward.
- Clicking or catching as the arm passes shoulder height.
How serious it is: Impingement and tendinopathy without a tear respond well to loading. A partial tear sits in between, and a full-thickness tear with real weakness, especially in a younger fighter after a traumatic event, is usually a surgical discussion.
Typical time out: Six to twelve weeks of rehab for impingement or tendinopathy. Four to six months after rotator cuff repair, with no grappling until the repair is protected and strength has returned.
See a doctor if: Get assessed if you cannot hold the arm up at all after an injury, if there is numbness down the arm, or if night pain keeps waking you.
What helps
- Progressive loading of the cuff and the shoulder blade muscles, which outperforms rest for impingement.
- Fix the training pattern: reduce overhead pulling volume and total clinch time while the tendon settles.
- Manual therapy and range work as support, not as the main treatment.
- Corticosteroid injection can buy a short window of pain relief to make rehab possible, but it is not a fix and repeated injections into a tendon are best avoided.
- Imaging and a surgical opinion if weakness is real and does not recover with eight to twelve weeks of proper rehab.
Neck Injuries (Strains, Cervical Spine Injuries)
Most neck injuries in MMA are strains of the deep and superficial neck muscles and sprains of the small facet joints between the vertebrae, from the head being whipped by a strike or cranked in a guillotine, headlock or scramble. The more serious version involves the discs or the nerve roots leaving the spine, which produces symptoms down the arm rather than in the neck itself.
Symptoms
- Stiffness and pain that is worse the morning after training.
- Difficulty turning the head fully to one side.
- A pulling pain into the top of the shoulder blade.
- Burning, tingling or numbness running down one arm.
- Headache that starts at the base of the skull.
How serious it is: A muscular strain settles in days to a couple of weeks. Nerve involvement, meaning arm pain, numbness or weakness, is a different category, and any suspicion of a bony or ligament injury to the cervical spine after a spike onto the head is an emergency.
Typical time out: One to three weeks for a simple strain. Six weeks to several months where a nerve root is irritated, and the return is guided by strength and symptoms in the arm, not by neck pain alone.
See a doctor if: Numbness or weakness in the arms or legs, loss of bladder control, or severe neck pain after a landing on the head means do not move the athlete and call for emergency help.
What helps
- Early gentle range of motion rather than a collar, since immobilizing a simple strain prolongs it.
- Progressive strengthening of the deep neck flexors and the upper back, which is protective in a sport built on head control.
- Reduce guillotine and crank exposure during recovery, and tap early on neck cranks as a standing rule.
- Imaging where arm symptoms, weakness or a high-energy mechanism are present.
- Look at how you shoot for takedowns: a lowered head on entry is a mechanism you can coach out.
Hand and Wrist Injuries (Fractures, Sprains, Dislocations)
The hand transmits the whole force of a punch through five thin metacarpal bones and small joint capsules. The classic boxer’s fracture is a break at the neck of the fifth metacarpal, behind the little-finger knuckle, when the punch lands off-axis. Grappling adds its own pattern: sprained and dislocated finger joints from grip fighting, thumb ligament injuries from a caught grip, and wrist sprains from posting on an extended hand. Hand injuries are among the most frequently recorded in professional MMA competition.
Symptoms
- Pain right at one knuckle or one finger joint rather than across the hand.
- A knuckle that has sunk or disappeared when you make a fist.
- Swelling that makes the finger stiff and sausage-shaped.
- Weak grip or pain when gripping a lapel or a wrist.
- Pain in the hollow at the base of the thumb, which raises the question of a scaphoid fracture.
How serious it is: Sprains and stable undisplaced fractures do well with taping or a splint. Rotation of a finger when you close the fist, joint surface involvement, and scaphoid fractures are the ones that need proper fixation, because a missed scaphoid can fail to unite.
Typical time out: Two to four weeks for a finger sprain with taped training, four to eight weeks for a metacarpal fracture, and eight to twelve weeks or more for a scaphoid, which is slow to heal by nature.
See a doctor if: Get imaging if a finger crosses over the others when you close your fist, if a knuckle is flattened, or if pain in the base of the thumb persists past a few days despite a normal first X-ray.
What helps
- Have hand pain that persists beyond a few days imaged, because scaphoid and small joint fractures hide behind swelling.
- Buddy taping and early controlled motion for stable finger injuries, since stiff fingers are the usual long-term cost.
- Wrap technique and glove fit reviewed by a coach, and reduced heavy-bag volume while the hand settles.
- Grip strength and finger extensor work to balance the constant flexion of gripping.
- Hand therapy rather than self-managed rest where the joint has been dislocated or the ligament torn.
Rib Injuries (Bruised, Fractured Ribs)
Ribs can be bruised, cracked, or separated at the cartilage where they meet the breastbone. In MMA the causes are body kicks landing on the lower ribs, knees in the clinch, and sustained compression under a heavy top position or a body triangle. Because the ribs move with every breath, the injury is felt constantly rather than only during training.
Symptoms
- Sharp pain on breathing in deeply, coughing, laughing or sneezing.
- Pain when rolling over in bed or getting up from lying down.
- A precise sore point you can locate with one fingertip.
- Shallow breathing because a full breath hurts.
- A click or grinding feeling over the front of the chest with a cartilage injury.
How serious it is: A bruise or a single undisplaced crack is painful but not dangerous. Multiple broken ribs, breathlessness, or pain over the lowest ribs where the spleen, liver and kidneys sit is a different matter and needs assessment.
Typical time out: Three to six weeks for a bruise, six to twelve weeks for a fracture, and cartilage injuries at the front of the chest are notoriously slow and can nag for three months or more.
See a doctor if: Go in the same day for shortness of breath, coughing blood, pain spreading into the shoulder tip, or pain over the lower ribs with faintness, which can mean bleeding inside.
What helps
- Keep breathing deeply on purpose several times an hour, because shallow breathing invites a chest infection.
- Pain control good enough to allow those deep breaths, discussed with a doctor.
- No rib belts or tight strapping, which restrict the lung.
- Return to light movement early and rebuild trunk rotation gradually, saving body sparring for last.
- Cover the body deliberately when you come back, since the same rib is the one that goes again.
Back Injuries (Muscle Strains, Herniated Discs)
The lower back is loaded in MMA by lifting a resisting opponent, bridging out from under top pressure, and repeated rotation in scrambles. A muscle strain damages the long spinal muscles and their attachments. A disc herniation is a bulge of the soft center of a disc pressing on a nerve root, and it is the arm or leg symptoms, not the back pain, that define it.
Symptoms
- A sudden catching pain when lifting or twisting.
- Muscle spasm that locks you to one side.
- Pain running down the back of one leg past the knee.
- Numbness or pins and needles in the leg or foot.
- Difficulty pushing off, standing on tiptoe or lifting the foot when walking.
How serious it is: A strain is painful and self-limiting. A disc problem is graded by nerve involvement: leg pain alone is common and usually settles, while progressive weakness in a leg is the sign that needs specialist review.
Typical time out: One to four weeks for a muscle strain. Six to twelve weeks for most disc-related leg pain treated without surgery, and three to six months after discectomy before full grappling.
See a doctor if: Numbness around the groin or buttocks, loss of bladder or bowel control, or a leg that is getting weaker means emergency assessment the same day.
What helps
- Stay moving and return to normal activity early; bed rest makes back pain worse.
- Progressive loading of the hips, trunk and back extensors instead of endless isolated core drills.
- Learn to lift and bridge with the hips rather than by flexing and rotating the loaded spine.
- Physiotherapy early where there is leg pain, and imaging only if symptoms persist or weakness appears.
- Modify training rather than stopping: stand-up and controlled positional work usually stay possible.
Facial Fractures (Nose, Jaw, Orbital Fractures)
The face has several bones that break at predictable points: the nasal bones, the thin floor of the eye socket, the cheekbone, and the jaw at its angle or at the condyle near the ear. A straight punch breaks the nose, an upward elbow or a hook to the cheek can blow out the orbital floor, and a hook to the point of the chin transmits force to the jaw joint. Nose injuries are among the most frequent injuries recorded in professional MMA bouts.
Symptoms
- A crack or crunch felt at impact with immediate heavy nosebleed.
- The nose or cheek looking flattened, pushed to one side or asymmetric.
- Double vision, especially when looking up, which points to the orbital floor.
- Numbness of the cheek, upper lip or gum on one side.
- Teeth that no longer meet properly, or pain in front of the ear when opening the mouth.
How serious it is: An undisplaced nasal fracture may only need observation. Displacement, double vision, a sunken eye, numbness in the cheek and any change in how the teeth meet indicate a fracture that needs surgical assessment within days, not weeks.
Typical time out: Bone healing takes six to eight weeks, and nasal fractures that need setting are best reduced within about two weeks. Expect six to twelve weeks away from contact, longer after jaw or orbital surgery, plus any commission suspension.
See a doctor if: Double vision, a bite that has changed, clear fluid running from the nose, numbness in the cheek, or a nose that will not stop bleeding all mean the same day to a doctor.
What helps
- Stop the bout or session and get a proper facial examination, including how the teeth meet and whether vision doubles.
- Imaging of the facial bones where displacement or an orbital fracture is suspected, since a plain look at the face misses these.
- Early referral for setting a displaced nose, because after two to three weeks it needs a bigger operation.
- Soft diet and avoiding nose blowing, which can push air into the tissues after an orbital or sinus wall fracture.
- A full return-to-contact clearance from the treating specialist, and a mouthguard that actually fits, since jaw force is transmitted through it.
First Aid for Soft Tissue Injuries: PEACE and LOVE
Sports medicine has moved on from RICE. The current guidance, published in the British Journal of Sports Medicine in 2019, splits care into the first days after the injury and everything that follows.
PEACE, the first two to three days
- Protect: unload the area and limit movement that hurts, but only briefly.
- Elevate: keep the limb above heart level when you can.
- Avoid anti-inflammatories: they may blunt the healing you need.
- Compress: a bandage or taping limits swelling.
- Educate: your body heals this on its own; passive treatments rarely speed it up.
LOVE, from day three onward
- Load: return to movement as pain allows, early loading builds tissue.
- Optimism: expectations shape recovery more than most people assume.
- Vascularization: easy cardio that does not hurt brings blood to the area.
- Exercise: restore strength, mobility and balance before returning to play.
Ice still helps with pain in the first hours. What changed is the evidence that long icing and routine anti-inflammatory drugs slow tissue repair.
How to Lower Your Risk in Mixed Martial Arts
- Treat hard sparring as a dose you schedule, not a default. Most head impact in MMA is accumulated in the gym rather than in bouts, and cutting hard head sparring to a small number of controlled rounds per week is the biggest single lever you have.
- Build the neck deliberately. Isometric and progressive neck work in all four directions gives the head something to resist rotation, and the neck is loaded in every clinch, guillotine and takedown defense.
- Make tapping early a gym rule, especially on heel hooks, knee bars and neck cranks. These give little warning before failure, so the decision has to be made before the pain, not during it.
- Load the tendons that the sport hammers: calves and Achilles for kicking and shooting, hips and hamstrings for takedowns, grip and forearms for grappling. Slow heavy strength work through full range beats stretching for injury prevention.
- Train the hand as a striking tool. Correct wrap technique, gloves that fit, and controlled progression of heavy-bag and hard-pad volume prevent the metacarpal and wrist injuries that make up a large share of MMA injuries.
- Fix the gym environment: mats without gaps at the fence line, a mouthguard fitted for you, shin guards in sparring, and cutting fingernails so eye injuries do not happen by accident.
When to Stop and Get Medical Help
Most of the injuries on this page are treated at home. These signs are not.
- Any loss of consciousness, seizure, repeated vomiting, worsening headache or confusion that deepens after a head impact.
- Numbness, tingling or weakness in the arms or legs, especially after a landing on the head or neck.
- A joint that is visibly out of place, a limb with an obvious bend, or bone breaking the skin.
- Inability to bear weight on a leg or to move a joint at all after an injury.
- Sudden change in vision: double vision, flashes, a shadow across the field of view or blood in the front of the eye.
- Shortness of breath, coughing blood, or pain over the lowest ribs with faintness, which can mean internal bleeding.

Frequently Asked Questions
How common are injuries in MMA compared with other sports?
MMA has one of the highest recorded injury rates of any sanctioned sport. A systematic review of competition studies found a weighted average of 246.4 injuries per 1,000 athlete exposures among male fighters, and ringside physician reports from 503 US contests found at least one injury in 57 percent of them. Note that these figures describe bouts, not training. Most of your total exposure is in the gym, which is where your prevention effort belongs.
What is the most common injury in MMA?
Facial lacerations. In a review of professional bouts sanctioned in Nevada, they made up 47.9 percent of all recorded injuries, ahead of hand injuries at 13.5 percent and nose injuries at 10.4 percent. Cuts dominate because elbows and head clashes split thin skin over the bony ridges of the face, and because they are visible enough that every one gets recorded.
How long do you have to stay out after a concussion in MMA?
Symptoms usually clear within one to four weeks, but that is not the same as being cleared to fight. Athletic commissions commonly impose suspensions of thirty to ninety days or more after a knockout, and you should pass through a stepwise return, from light aerobic work to non-contact drilling to contact, with a doctor signing off. The one rule with no flexibility is that you never return to sparring while any symptom is still present.
How do you treat a sprain or strain if RICE is out of date?
The current approach is to protect the injury briefly, then load it progressively rather than resting it until pain disappears. Short cooling in the first hours is fine for pain, but prolonged rest, tight wrapping and elevation as a multi-week recipe slow recovery. What actually rebuilds the tissue is graded strengthening of the injured muscle or ligament, balance work for joint injuries, and a return guided by strength and function rather than by the calendar.
Can you keep training while injured?
Usually yes, but not the same training. Almost every MMA injury leaves large parts of the body available: a hand injury still allows kicking and conditioning, a rib injury still allows light stand-up. The exceptions are concussion, where you stop all contact and let symptoms guide even light exercise, and any injury where loading risks making a break or tear worse. Ask what you can load, not just what you must avoid.
Are cortisone injections a good idea for a nagging tendon problem?
They are an exception, not a routine treatment. An injection can reduce pain for a few weeks, which is sometimes useful to make rehab possible, but for tendinopathy the longer-term results tend to be worse than with loading alone, and repeated injections around a tendon are best avoided. Slow, heavy, progressive loading with eccentric work is the treatment that actually changes the tissue.
