Cornerbacks Shawn Springs and Walt Harris returned to practice on Friday and remain listed as probable for Sunday's game against the Dallas Cowboys.
However, cornerback Carlos Rogers, linebacker LaVar Arrington and safety Matt Bowen were downgraded to questionable after they both missed Friday's practice.
Rogers has been sidelined with a biceps injury, Arrington has a thigh injury and Bowen has a knee injury.
If Rogers is unable to play, third-year cornerback Ade Jimoh would likely see increased playing time. The possibility remains that the Redskins could sign a cornerback from the practice squad before Sunday's game.
Springs has been sidelined with a groin injury and Harris has a calf injury.
Arrington took some light drills during practice, but he did not participate in team work.
"LaVar got back out there and took some work," head coach Joe Gibbs said. "So that was good. He's been around here a long time and it's a big game for him. It's the biggest game that he's been a part of. So he got back out and took some work. We'll just have to see what we think."
If Arrington is deactivated, Warrick Holdman would likely start in his place.
Several of the injured players will be game time decisions, Gibbs added.
Left tackle Chris Samuels also missed practice on Friday, likely to give his knee injury another day of rest. He remains listed as probable for Sunday's game.
-- PRACTICE SQUAD: MORTON RETURNS
The Redskins re-signed cornerback Christian Morton, who was with the Redskins earlier this season, to the team's practice squad on Friday. Morton spent time on the Redskins' practice squad in early September, but later signed with the Atlanta Falcons.
Morton played in four games with the Falcons, recording five tackles and two passes defended, before being released.
Morton, a second-year player, was a seventh-round draft pick by the New England Patriots in 2004. He played in two regular-season games and two postseason games, including the NFC Championship game, with the Falcons in 2004.
To make room for Morton on the practice squad, the Redskins released rookie linebacker Zak Keasey from the practice squad.
-- COOLEY ON DALLAS WEEK
Second-year H-back Chris Cooley grew up in Utah, so the Redskins-Cowboys rivalry wasn't exactly on his radar screen as a youth.
When he first moved to the Washington, D.C., area, Cooley got his first taste of it when fans welcomed him to the Redskins by saying, "Beat Dallas."
"At this point, I don't think anyone needs to say anything to us," Cooley said. "We know how big this game is. We're going to play with everything we have. Everyone wants it bad."
Cooley said he is not one to get uptight before big games. That's fitting to his typically laid-back personality.
"I try to take a pretty relaxed attitude toward big games," he said. "I mean, I play hard every play, but I don't get overly wound up. If I do, I sometimes don't play as well."
