If he wants to address the issue then do as somebody suggested in the comments, make the "injured" player sit out the rest of the series. You know, for his safety.
Bingo. Never happen, though. Way too much howling about it, players trying to play through injuries to stay in game, etc. Maybe a 3 play minimum instead of 1. 95% of time a real injury is out that long or longer anyway.
But the Giants one was soooo obvious, it was pathetic. Guys looking at sideline, two guys slooooowly fall to ground, then one immediately gets back up. Crassic.
