Head injuries in football are increasingly common. The nature of the game lends itself toward them, even with rules that prohibit helmet to helmet hits.
Plus, it's tough to determine whether a player has a concussion in the middle of game, especially when all that player wants to do is keep playing.
But if Dennis Molfese's idea goes according to plan, testing for concussions could become a lot faster and a lot easier. Molfese is the director of the University of Nebraska's Center for Brain, Biology and Behavior also known as CB3.
