The Redskins could be without several key players on Sunday when they take on the Tampa Bay Buccaneers.
Williams is recovering from a bone bruise in his right knee, and was able to practice in a limited capacity on Friday. If he is unable to play, Maurice Hurt will likely fill in.
Two wide receivers -- Pierre Garcon (foot) and Brandon Banks (hip) -- are also listed as questionable. Garcon has not played since Week 1, when he caught four passes for 109 yards. Banks caught one pass last weekend against the Bengals.
Finally, backup cornerback Cedric Griffin will not play: he is out with a hamstring injury.
