The Centers for Disease Control and Prevention says about 300,000 Americans suffer sports-related concussions annually.

This injury can be very serious, and can be difficult to detect, as the injury is functional, rather than structural. Concussions are under reported as athletes do not believe injury is serious and often resist leaving a game or practice. However there are signs coaches can observe that indicate a concussion has occurred including player appears dazed, confused, unsure of game or opponent, answers questions slowly, or forgets events prior or after the injury. Symptoms reported by the athlete include headache, nausea, sensitivity to light or noise, feeling sluggish, and even change in sleep pattern. There are on field tests coaches can conduct.
