Dante Rosario, TE (hamstring)
Jarret Johnson, OLB (back)
Whatever your thoughts on Clary, the offensive line can't really afford for him to get taken out of the lineup any time soon. Butler hurts more than almost anyone else on the roster except Weddle, but we'll see how Jonas Mouton can do in his absence.
Eddie Royal has been a bust as a free agent signing, just as much as Robert Meachem, because of his inability to get healthy.
Mohamed Sanu, WR (foot)
Richard Quinn, TE (hamstring)
Mohamed Sanu being out helps. He's a solid WR and has been their Wildcat QB, so his absence hurts the offense in both ways. Green-Ellis' ankle injury also helps San Diego, but he's been good enough in recent weeks that I wouldn't count on it being a big hindrance for him.
