If you suspect that an athlete has a concussion, or if any of the conditions listed on the left panel are true, you should take the following four steps;

1. Remove the athlete from play or practice
   
2. Ensure the athlete is evaluated by a health care professional experienced in evaluating for concussion.  Do not try to judge the seriousness of the injury yourself.
3. Inform the athlete's parents about the possible concussion and give them the CDC Fact Sheet for Parents on Concussion.
4. Submit an "Incident Report"
5. Keep the athlete out of play the day of the injury and until a health care professional, experienced in evaluating for concussion, says they are symptom-free and it's OK to return to play.
