Not at all, they'll keep him until he startes losing. Which, since the "leg injury" stuff was all a bunch of crap, I'd say that won't be for at least another 2 or 3 seasons. We're talking about a guy who doesn't throw that much, doesn't run at all, so I'm pretty sure he can still hand it off with a messed up face.
In all seriousness, I feel bad for the guy. Prime of his life, on top of the world, and this happens. Hopefully others can look at this accident and see that everything can be taken away in seconds. Appreciate life and be smart. Even though MI is passing the "no helmet" law, I'd still never get on road w/o wearing one.
