Locker Room Buzz: Buffalo Bills

EAST RUTHERFORD, N.J. -- Observed in the locker room after the Buffalo Bills' 27-20 loss to the New York Jets:

Mario Williams' status unclear: Williams played sparingly in the late stages of the game, prompting speculation that he could be injured. Head coach Doug Marrone told reporters that he saw trainers working on Williams but had yet to speak to the medical staff, adding that coaches were discussing using Jamaal Westerman in that role late in the game. About an hour after the game, with every locker empty except for Williams', a team spokesperson said Williams was undergoing treatment and would not have time for comment.

Carrington in leg brace: Defensive lineman Alex Carrington, who was carted off the field late in the fourth quarter, limped around the locker room after the game. He was initially wearing a bandage wrap over his left knee and was later spotted wearing an immobilizing brace over that knee. A trainer assisted him dressing. Offensive lineman Kraig Urbik, who briefly left the game, also had a wrap on his left knee but was moving well.

No sign of Spiller: Running back C.J. Spiller, who left in the third quarter with a knee injury, was not spotted in the locker room after the game. His locker was empty by the time reporters entered.
