The New York Times in Player Silence on Concussions May Block N.F.L. Guidelines by Alan Schwarz, reported that Troy Vincent, President of the NFL Players Association, said:

“I’m not sure if we, as athletes, know what a concussion is just listening to these doctors and researchers talk. Outside of me being knocked out, asleep, I went back in the game on all the other occasions. And 50 or 60 times, I’m in the huddle, I don’t know where I’m at, don’t know the call, and I’ve got a player holding me up. I’m not sure if athletes really know what a concussion is — get some smelling salts and back in the game.”

These words of wisdom came at a “Concussion Conference”, held by the league, on June 19^th in Rosemont, Illinois.
