Doubtful: CB Devin McCourty (shoulder)
Questionable: CB Kyle Arrington (foot), S Patrick Chung (foot), G Dan Connolly (groin), DE Shaun Ellis (rib), RB Kevin Faulk (knee), RB BenJarvus Green-Ellis (toe), LB Gary Guyton (shoulder), S James Ihedigbo (shoulder), WR Taylor Price (hamstring), WR Matt Slater (shoulder), T Nate Solder (concussion), LB Jeff Tarpinian (illness), T Sebastian Vollmer (back)
McCourty missing the game is a big one as New England is already banged up in the secondary. I'm not really sure how to view that injury -- on the one hand, McCourty missing the game takes a good player out of the secondary but on the other hand the passing game isn't exactly KC's strength entering this game. We'll see how it goes.
The two probable guys, Waters and Welker, should play and that's big for the Patriots as both players are playing at a high level.
