I agree. 1 game automatic (unless there's a bye week following the concussion) is a good rule to put in place. It takes away the temptation and guessing games. Although it could make it more tempting to not diagnose the concussion in the first place. I guess it goes hand in hand with having a third party doctor, agreed to by the players and ownership, evaluate the player. Even with that there are going to be situations where the players can and do hide them.
