As the coach, you don't have to diagnose the concussion. Your job is to recognize a possible concussion by observing two things: (1) a blow to the head or body that is concerning and (2) any sign or symptom that tells you something may not be right with the athlete. Use the Signs & Symptoms information to assist or the CDC clipboard sticker.. If you have a reasonable suspicion that these two indicators are present, follow the motto When in doubt, sit them out. This means that if you suspect a concussion may have occurred, you should immediately pull the athlete out of practice/play, inform their parents about what happened, and direct the parents to information about concussions, and how to get medically evaluated.
A concussion is defined as a direct or indirect force to the head (could be a direct hit or a whiplash-type injury) that results in neurological impairment (e.g., signs & symptoms). If you see or are told that a child has received a blow, you should ask specific questions about their condition.
