Football is a collision sport, and injuries are part of its reality at every level. Many cannot be eliminated, but good technique, conditioning, equipment and rules reduce their frequency and severity.

The most common injuries
- Concussions: brain injuries caused by a blow to the head or body. Symptoms include headache, dizziness, confusion, nausea and sensitivity to light.
- Knee injuries: sprains and ligament tears (ACL, MCL), often from cutting or contact to the side of the knee.
- Ankle sprains, including high ankle sprains, which take longer to heal.
- Shoulder injuries: separations and dislocations from tackling and falls.
- Hand and finger injuries for linemen and receivers.
- Hamstring and groin strains from sprinting.
Quarterback injuries
Quarterbacks face specific risks: shoulder and elbow strain from throwing, ankle and knee injuries when hit in the pocket, and concussions from blindside hits. Rules protecting passers (roughing the passer) exist for this reason. A strong offensive line and quick decisions protect a quarterback more than anything.

Concussion: what to do
Any player with a suspected concussion should be removed from play immediately and not return the same day. Return to sports should follow a gradual, step-by-step progression and be cleared by a healthcare provider. The CDC’s HEADS UP program explains how to respond.
Prevention
- Tackling technique: keeping the head out of contact; see safe tackling technique.
- Conditioning: strong neck, shoulders, hips and legs absorb force better; fatigue increases injury risk late in games.
- Equipment: a properly fitted helmet, shoulder pads and mouthguard. See choosing football equipment.
- Limits on contact in practice: many leagues now restrict full-contact practice time.
- Heat precautions: acclimatize gradually in summer, drink regularly and watch for heat illness.
Do not play through warning signs
Pain that persists, swelling, instability in a joint or any head symptoms need medical attention. Playing through injury often turns a short absence into a long one.
