As a coach, if you think an athlete may have a concussion, you should:
- Remove the athlete from play.
- Keep an athlete with a possible concussion out of play on the same day of the injury and until cleared by a health care provider. Do not try to judge the severity of the injury yourself. Only a health care provider should assess an athlete for a possible concussion.
- Record and share information about the injury, such as how it happened and the athlete’s symptoms, to help a health care provider assess the athlete.
- Inform the athlete’s parent(s) or guardian(s) about the possible concussion and refer them to CDC’s website for concussion information.
- Ask for written instructions from the athlete’s health care provider about the steps you should take to help the athlete safely return to play. Before returning to play an athlete should:
- Be back to doing their regular school activities.
- Not have any symptoms from the injury when doing normal activities.
- Have the green-light from their health care provider to begin the return to play process.
