In December of 2009, the NFL adopted a stricter statement on return-to-play procedures following concussions, which may be worth reviewing in the wake of Jay Cutler suffering a concussion in Sunday night's 17-3 loss to the Giants at New Meadowlands Stadium.
What follows was copied from the NFL's website.
"The statement advises that a player who suffers a concussion should not return to play or practice on the same day if he shows any signs or symptoms of a concussion that are outlined in the return-to-play statement. It further states:
"Once removed for the duration of a practice or game, the player should not be considered for return-to-football activities until he is fully asymptomatic, both at rest and after exertion, has a normal neurological examination, normal neuropsychological testing, and has been cleared to return by both his team physician(s) and the independent neurological consultant. A critical element of managing concussions is candid reporting by players of their symptoms following an injury. Accordingly, players are to be encouraged to be candid with team medical staffs and fully disclose any signs or symptoms that may be associated with a concussion."
