Oh I have no doubt he'll be in fine physical shape by next week - local talk is that he's probably exaggerated the injury to get out of practice.
What I do think though, is that Parcells will have him on the bench by week 8. If the Cowboys don't win (and with their absolutely pathetic O-line it's a strong possibility) T.O. will start running his mouth and causing tons of trouble, just like he has everywhere he's ever been.
