The Washington Redskins get back to work today, making preparations for Sunday’s game at Philadelphia.

With a victory, they remain in the driver’s seat in the NFC East. With losses by the New York Giants, Chicago Bears and Minnesota Vikings, the Redskins would clinch a playoff berth.

Nipping at the Redskins’ heels are the Dallas Cowboys, who also own an 8-6 record, and host the New Orleans Saints.

As they prepare for yet another crucial weekend, the Redskins have uncertainty looming over several areas.

Quarterback Robert Griffin III hopes to return to action on Sunday, but first needs the clearance from team doctors regarding his sprained LCL in his right knee. He moved well on Friday in the final practice leading up to the game against Cleveland, and did well during pregame workout Sunday, but was held out of action. Afterwards, Griffin said he believed he could have played. The following day, Mike Shanahan said that the doctors would decide Griffin’s status for this week. He also said as soon as Griffin receives the green light, he returns as a starter – no sitting him to be extra cautious as a result of Kirk Cousins’ impressive outing versus the Browns.

Based on how Griffin looked, I’d be surprised if he’s not back in the saddle at Philadelphia. We’ll see how things play out in this first practice today.

Today also should yield some clarity regarding Will Montgomery’s status. Shanahan declined to discuss his MCL strain in any detail on Monday, and said, “We’ll talk about Will more on Wednesday.” The Redskins also will be monitoring the status of starting right tackle Tyler Polumbus, who suffered a concussion Sunday. Without Polumbus, their current options are Maurice Hurt, who has never played a regular season game at tackle, or rookie Tom Compton, who hasn’t dressed for a game this season. The Redskins didn’t make a move on Tuesday to bring in any help on the offensive line – even given the suspension of Jordan Black – but they could be forced to if Polumbus’ concussion symptoms linger.

The team did, however, make an attempt to help their secondary, putting in a waiver claim for eight-year veteran Dimitri Patterson, whom Cleveland released Monday. But the Redskins lost out in their claim to Miami, who had a higher waiver priority based on their inferior record.

Patterson had appeared in seven games (starting four) for Cleveland this season. (He actually got his start in the NFL with the Redskins in 2005).

The Redskins also released practice squad linebacker Kourtnei Brown two weeks after signing him, but they didn’t immediately replace him.

They entered Wednesday with both a vacant spot on the 53-man roster and an open spot on the practice squad.

UPDATE 11:20 a.m.: The Redskins announced Wednesday morning that they have signed linebacker Vic So’oto to their 53-man roster, and guard Pat Boyle to their practice squad.
