In the case of being told/not being told, it becomes a he said-he said issue. At the same time, helmets are usually taken away from players who are concussed or injured in some other way so that they can't insert themselves into the game. Thirdly, if a doctor or medical staff saw the player going in, s/he has the right to pull him. If Butch overruled the medical staff, then he's in trouble. Bottom line: I think people are making up a scenario that didn't happen.
