Washington Redskins offensive tackle Tyler Polumbus was able to practice on Thursday in a limited capacity, and is listed as questionable for Sunday's game against the Dallas Cowboys. Polumbus is recovering from a concussion that he suffered in Week 15. He was forced to sit out last week against the Philadelphia Eagles due to lingering symptoms. Polumbus practiced last week, but was never cleared by a neurologist to play.

Safety DeJon Gomes is recovering from a knee injury, and is also listed as questionable. Gomes partially tore his MCL last week against the Eagles. The tear is not considered serious, and he could play as early as this week.

The Redskins have a handful of players listed as probable, all of whom are expected to play on Sunday: linebacker London Fletcher (ankle), linebacker Lorenzo Alexander (shoulder), defensive end Stephen Bowen (biceps), wide receiver Pierre Garcon (foot), quarterback Robert Griffin III (knee), linebacker Ryan Kerrigan (ankle), center Will Montgomery (knee), wide receiver Josh Morgan (hand), left tackle Trent Williams (thigh), cornerback Josh Wilson (shoulder). Besides Fletcher, all of the probables were full participants in Thursday's practice.
