Redskins coach Mike Shanahan said left tackle Trent Williams is questionable for Sunday’s game against Tampa Bay after being able to practice on a limited basis on Friday.

Williams has a bone bruise in his right knee.

Also listed as questionable are receivers Pierre Garçon (foot) and Brandon Banks (hip).

Starting strong safety Brandon Meriweather and running back Evan Royster are probable after being limited by knee injuries.

Meriweather hasn’t played yet this season while Royster suffered his injury last Sunday.

Backup cornerback Cedric Griffin has been ruled out with a hamstring injury.
