Though repetitive closedhead injuries are often experienced in professional contact sports, many injuries are minor, with collisions involving the head an everyday experience of the sport. Collegiate football players can sustain anywhere from 400 to more than 2,400 head impacts per season, depending upon the player — and possibly his position. The athlete usually walks it off, or is examined and benched for a period of time, lives to play another day. Eventually he joins the NFL, retires, starts endorsing products, and, except for maybe gaining a few pounds, seems to suffer few ill effects.
