It's a bit surprising that the Raiders haven't simply shut Seymour down at this point with only one more game for him to possibly play in. Additionally, there's little incentive for him to return with the Raiders simply playing for pride and Seymour being a free agent in 2013.
WR Juron Criner (hip) and SS Tyvon Branch (neck/ankle) could sit out Sunday's game as well after being listed as questionable by team officials. Criner seems the likelier of the two to be ready after participating in practice for three consecutive days in a limited capacity. Branch was also limited Friday but only after resting the previous two days.
As for the rest of the Raiders injury report, DB Phillip Adams (concussion), T Khalif Barnes (triceps), TE Richard Gordon (biceps) and SS Mike Mitchell (neck) were all handed a probable tag. Adams availability is a bit surprising considering he's suffered two concussions in the past three games but apparently he's a quick healer.
