Albert Haynesworth was inactive for Sunday's game against the Dallas Cowboys.
Haynesworth missed practice all last week due to a sprained ankle, but he was able to test it running on a treadmill on Friday. He was listed as questionable heading into the game.
It's Haynesworth's first missed game after nine consecutive starts this season. He has 42 tackles, three sacks and 19 quarterback pressures this season.
With Haynesworth sidelined, the Redskins' 25th-ranked run defense was tested against the Cowboys' three-headed rushing attack of Marion Barber, Felix Jones and Tashard Choice.
Kedric Golston drew the start at defensive tackle next to Cornelius Griffin.
Golston has 28 tackles, one sack, one forced fumble and seven quarterback hurries this season,
Anthony Montgomery was active for the first time this season and he served in a backup role. Lorenzo Alexander and Phillip Daniels also slid over from end to play defensive tackle.
Speaking of the little-used Montgomery, head coach Jim Zorn said last week: "He has been doing a great job of fitting in as a teammate because he wants to be in there. You work hard, you try to prepare and get ready for the game and then you don't get to do anything. That's hard on a player and I really commend what Anthony has done.
"He has really hung in there and he has done everything we have asked him to do. I think when we call on him, he will be ready to go, and he'll answer the call."
Haynesworth, who made the trip to Dallas, joined Clinton Portis (concussion) and Chris Cooley (ankle) as starters out for the game.
The Redskins' complete list of inactives was as follows: Kevin Barnes, Portis, Eddie Williams, Cooley, Robert Henson, Mike Willliams, Haynesworth and Renaldo Wynn.
-- SMOOT STARTS IN PLACE OF ROGERS
Cornerback Fred Smoot drew the starting assignment ahead of Carlos Rogers on Sunday.
Rogers saw action as a replacement for an injured DeAngelo Hall, though. Hall suffered a knee contusion in the first quarter, but returned to the game.
It was Smoot's second start this season. He also started the Week 6 game vs. Kansas City.
Last week, Rogers was benched in favor of Smoot after he was beat on a double move by Denver Broncos wide receiver Brandon Marshall. The play resulted in a 40-yard touchdown pass.
Coaches praised Rogers for how he responded to the benching.
"I expect Carlos to bounce back, be the physical guy that he is, and go out there and cover wide receivers," secondary-cornerbacks coach Jerry Gray said. "Last year when we lost Shawn Springs [to injury against Dallas], we put Carlos on T.O. and he knocked three or four balls away during that game.
"It's just going through your progression, keep your eyes on the wide receiver and then make a play. Don't try to make a play that's not there."
Head coach Jim Zorn indicated last week there was a possibility that Rogers could reclaim the starting job.
