One thing that needs to be noted here is that a Concussion is one of those injuries that can occur where the "patient" is the only one who is aware of it. Not trying to pile on top of Pierce here, but if he is feeling light-headed, dizzy, nauseous, etc., it's up to him to report to the Training Staff. Remember Russell Allen from a few years ago? He had the potential of dying on the field and no one knew about it but him. He didn't even mention it until after the game.

 

If the player doesn't come forward about it, how is anyone else supposed to know?
