Football produces more injuries overall, but hockey is more dangerous in some specific and surprising ways. The answer depends on what kind of danger you’re asking about: total injuries, concussions, spinal cord damage, or long-term brain disease. Football wins on sheer volume of injuries and long-term brain damage, while hockey carries a higher risk of catastrophic spinal injuries and, in youth players, a higher concussion rate per exposure.
Overall Injury Rates Favor Hockey’s Safety
At the collegiate level, football has the highest injury rate of any sport studied: 35.9 injuries per 1,000 game exposures and 9.6 per 1,000 practice exposures. Men’s ice hockey comes in significantly lower at 16.3 injuries per 1,000 game exposures and just 2.0 per 1,000 practice exposures. That means a football player is roughly twice as likely to get hurt during a game and nearly five times as likely to get hurt during practice compared to a hockey player.
The practice gap is especially telling. Football practices involve full-contact drills, blocking, and tackling at high intensity. Hockey practices, by contrast, involve far less body contact than actual games, which explains the enormous difference between practice and game injury rates in that sport.
Concussions Tell a More Complicated Story
This is where hockey closes the gap and, for younger athletes, actually surpasses football. Among youth players, ice hockey produces 1.20 concussions per 1,000 athletic exposures compared to 0.53 for football. That makes youth hockey players more than twice as likely to sustain a concussion on a per-exposure basis.
The causes of hockey concussions reveal why. About 35% of youth hockey concussions come from a player’s head hitting the ice surface. Another 27% result from collisions with the boards or glass, and 25% from head-to-player contact. In other words, the rigid environment surrounding hockey players (ice, boards, glass) creates impact surfaces that don’t exist on a football field. Football concussions come almost entirely from player-to-player collisions, but the sheer number of those collisions over a game or season adds up.
When looking at concussions that cause a loss of consciousness in children ages 4 to 13, football accounts for 43% of all cases across major youth sports. Basketball and soccer follow at 21% and 18% respectively. Hockey didn’t rank in the top tier for loss-of-consciousness events, likely because far fewer children play organized hockey compared to football.
Impact Forces Are Higher in Hockey
A standard hockey body check delivers more force to the head than a standard football tackle. Measurements taken inside helmets during routine, non-injurious play found peak accelerations of 35 g in hockey compared to 29.2 g in football. That difference is statistically significant and reflects the physics of each sport: hockey hits happen at higher speeds on a low-friction surface, and players often cannot brace for impact the way a football player might before a tackle.
Despite these higher forces, hockey helmets outperform football helmets in reducing the energy that reaches the skull. Collisions between two modern hockey helmets produce significantly lower g-forces than collisions between two modern football helmets. Hockey helmet design, with its harder outer shell and different energy-absorption approach, appears to do a better job managing the specific type of impacts the sport produces. Football helmets sit in an intermediate zone, better than the old leather helmets but not as protective as hockey helmets in controlled testing.
Spinal Cord Injuries Are More Common in Hockey
This is the category where hockey is clearly more dangerous. Among American high school-aged athletes, the rate of catastrophic injury from hockey is 2.56 per 100,000 participants, compared to 0.68 per 100,000 in football. The rate of paralysis from spinal cord injury is at least three times higher in Canadian hockey than in American football.
The mechanism is typically a check from behind that drives a player headfirst into the boards. The rigid wall surrounding a hockey rink creates a collision surface with no give, and players traveling at speed have little ability to protect themselves. Football spinal injuries, while they do occur, have decreased substantially since rule changes in the late 1970s banned “spearing” (leading with the crown of the helmet). Hockey has implemented similar rules against checking from behind, but the boards remain an unchangeable hazard.
Long-Term Brain Damage and CTE
Football’s greatest danger may not show up during a player’s career at all. The Boston University CTE Center has diagnosed chronic traumatic encephalopathy (CTE) in 345 of 376 former NFL players whose brains were studied after death. That’s 91.7%. For context, a separate study of 164 brains donated by people from the general population found CTE in just 0.6%.
These numbers carry an important caveat: the NFL brains were donated by families who suspected something was wrong, so the sample is not random. Still, the sheer scale of the finding points to something deeply concerning about the cumulative effect of repeated head impacts in football. It’s not just concussions that cause CTE. It’s the hundreds of sub-concussive hits that linemen absorb on every play, snap after snap, season after season.
Hockey players also develop CTE, but no comparable large-scale brain bank study of former NHL players has been published. The sport involves fewer total head impacts per game than football, where offensive and defensive linemen collide on every single play. A hockey player may take a handful of hard body checks per game; a football lineman absorbs 40 to 60 head impacts in the same period. That volume difference likely explains why football dominates the CTE conversation.
Knee and Lower Body Injuries
Football is harder on knees and lower extremities. The planting, cutting, and tackling motions in football place enormous stress on the ACL and MCL. Hockey players do sustain knee ligament injuries, but at a much lower rate. Collegiate male hockey players experience MCL injuries at a rate of about 0.44 per 1,000 athlete exposures, with most caused by player-to-player contact. Severe tears (grade 3) are uncommon, and ACL involvement is rarer still.
Football’s playing surface contributes to the problem. Cleats gripping turf or grass lock the foot in place during a hit, transferring rotational force directly to the knee. Hockey skates on ice allow the foot to slide, which dissipates some of that energy. The tradeoff is that hockey’s slippery surface makes it harder to brace for impacts, contributing to those higher head accelerations.
Female Athletes Face Different Risks
Research consistently shows that female athletes sustain concussions at higher rates than male athletes in the same sports, even though they receive fewer impacts at lower magnitudes. Women also report more severe symptoms and have worse outcomes after concussion. In women’s ice hockey, which prohibits body checking, concussions still occur frequently from incidental contact, collisions with the boards, and falls to the ice.
The reasons for this gender gap aren’t fully understood, but differences in neck strength, hormonal factors, and possibly a greater willingness to report symptoms all play a role. For families weighing the safety of either sport for a daughter, the concussion risk in women’s hockey is real despite the no-checking rule.
Which Sport Is Actually More Dangerous
If you define danger as the total likelihood of getting hurt on any given day, football is more dangerous by a wide margin. If you define it as the risk of a life-altering spinal injury, hockey is more dangerous. If your concern is long-term brain health over a full career, football poses the greater threat because of the sheer volume of repetitive head impacts, particularly for linemen.
For youth athletes, the picture shifts. Young hockey players face a higher per-exposure concussion rate than young football players, and the rigid playing environment (ice, boards, glass) introduces hazards that a grass or turf field simply doesn’t have. Both sports have made significant rule changes to reduce dangerous plays, but neither has eliminated the fundamental physics that make high-speed collisions between large athletes inherently risky.
