The 15 Most Common BJJ Injuries (and How to Avoid Them)

Brazilian Jiu-Jitsu is one of the most rewarding martial arts in the world, but it is also physically demanding. Because training involves joint locks, takedowns, scrambles, and pressure, injuries can happen. The good news is that most injuries are preventable with the right habits, awareness, and training approach.

This guide breaks down the fifteen most common BJJ injuries and how to avoid them, especially for beginners and hobbyists who want to train consistently without long layoffs.

1. Finger Sprains and Joint Damage

• Caused by gripping the gi too hard or getting fingers caught in sleeves and collars.

• Prevention: Use proper grip breaks, tape fingers, and avoid death-gripping.

2. Rib Injuries

• Often from heavy pressure or twisting under side control.

• Prevention: Improve framing, avoid explosive bridging, and tap early during compressive submissions.

3. Shoulder Strains and Rotator Cuff Issues

• Common from kimuras, Americanas, and bad breakfalls.

• Prevention: Strengthen rotator cuff muscles, learn correct falling mechanics, and tap early.

4. Elbow Hyperextensions

• Usually from armbars or posting your arm out during a fall.

• Prevention: Keep elbows tight, avoid posting, and respect armbar pressure.

5. Knee Ligament Injuries

• Often from heel hooks, takedowns, or awkward guard retention.

• Prevention: Warm up properly, avoid twisting under pressure, and learn safe leg lock defence.

6. Ankle Sprains

• Caused by footlocks or getting caught in scrambles.

• Prevention: Strengthen ankles, avoid rolling with reckless partners, and tap early to footlocks.

7. Neck Strains

• From guillotines, triangles, and being stacked.

• Prevention: Strengthen neck muscles, avoid resisting deep submissions, and improve posture.

8. Lower Back Pain

• Often from guard retention or poor hip mobility.

• Prevention: Stretch hips and hamstrings, strengthen core, and avoid muscling techniques.

9. Cauliflower Ear

• Caused by repeated friction or impact.

• Prevention: Wear headgear, avoid grinding your head, and treat swelling early.

10. Toe and Foot Injuries

• From getting toes caught in the mat or gi.

• Prevention: Keep nails trimmed, avoid explosive pivots, and tape weak toes.

11. Bruised Ribs

• Common for beginners learning to frame.

• Prevention: Improve defensive structure and avoid twisting under pressure.

12. Wrist Sprains

• From posting or resisting wristlocks.

• Prevention: Keep hands close to your body and avoid stiff-arming.

13. Hip Flexor Strains

• Often from overusing guard.

• Prevention: Strengthen glutes, stretch hip flexors, and vary your game.

14. Cuts and Mat Burns

• From friction against the mat or gi.

• Prevention: Moisturise skin, wear rashguards, and keep technique clean.

15. Concussions

• Rare but possible during takedowns.

• Prevention: Learn proper breakfalls and avoid uncontrolled stand-up sparring.
