Right, and as I said in other posts. If they can show an Xray that the foot isn't 100% in November/December, they are going to be ok. However, if they get full participation clearance from the medical staff and he is cleared, the waiver isn't possible.
There's too much unknown right now in the situation and will all depend on what the medical staff can show/prove. If (as we've been told) McCall has been cleared (and by cleared, meaning documented full participation), then he can't get the waiver.
My hope is if McCall doesn't play, they can prove it was a season-ending injury. If they don't think they can prove it, then McCall is best used in the game.
