Concussion is an "invisible injury"

We cannot physically see where and when a person has been concussed as concussion manifests in an internal manner that is difficult to identify, understand and explain.

Any athlete with a suspected concussion should immediately be removed from practice or play and not return to play until assessed medically, even if their symptoms resolve.

Symptoms may not be present at the time of injury, but may evolve over minutes, hours and days.

Athletes will always want to play on. They might not know that they might be concussed, and they will make bad decisions after a head impact – do not let the athletes decide.

Continued play after suspected concussion may result in prolonged symptoms, longer time away from sport, increased risk of new injury, second impact syndrome, or other long term consequences.
