The Redskins listed two changes on the the team's injury report on Thursday: right tackle Jon Jansen was upgraded to probable and linebacker Marcus Washington was downgraded to doubtful.
Jansen returned to practice for the first time since Dec. 8. The veteran right tackle has been battling calf soreness for several weeks, and the injury forced him to sit out last Sunday's game against the New Orleans Saints.
After Thursday's practice, Jansen said that his calf has been "feeling a lot better" thanks to the extra week of rest.
Team officials had expected to re-address Jansen's status on Friday, but opted to upgrade him on Thursday after he participated in practice.
Meantime, Washington suffered a sprained knee in last Sunday's 16-10 win over the New Orleans Saints at the Superdome, assistant head coach-defense Gregg Williams said.
If Washington cannot play, Williams and linebackers coach Dale Lindsey could employ a number of packages with veterans Jeff Posey and Warrick Holdman seeing action.
Posey is listed as Washington's backup at strong-side linebacker. However, the team could shift weak-side starter Holdman to strong-side and give rookie Rocky McIntosh extended playing time. McIntosh saw action at weak-side during last Sunday's 16-10 win over the New Orleans Saints.
"What we've done in there is, we've had Jeff in there, we've had Warrick in there, and we've had a lot of different packages rotating in," Williams said after Thursday's practice. "We'll get the best guys out there."
It would be the first game since 2004 that the durable Washington would miss in his three seasons with the Redskins.
Said Williams: "Marcus us a tough football player and a very good inspirational leader, but it's always an opportunity for somebody else to step up."
