The Redskins placed right guard Randy Thomas on injured reserve on Tuesday, officially ending the veteran lineman's season.
Thomas suffered a fractured fibula in his right leg during Sunday's 35-7 win over the Dallas Cowboys.
Taking the place of Thomas on the 53-man roster is rookie offensive lineman Ikechuku Ndukwe, who has spent the last seven weeks on the Redskins' practice squad.
Ndukwe, 6-4 and 320 pounds, also spent time on the New Orleans Saints' practice squad earlier this season. He was a left guard at Northwestern and started in 2003-04 for the Wildcats.
The Redskins also signed offensive lineman Jim Jones and tight end David Kashetta to the practice squad on Tuesday.
Jones is a third-year player who has had NFL stints with the Pittsburgh Steelers, Baltimore Ravens and Houston Texans. The 6-3, 315-pounder played his college ball at Notre Dame, playing mostly left guard.
Kashetta, 6-3 and 247 pounds, is a rookie out of Boston College who originally signed with the Redskins as an undrafted free agent in April 2005. He was released one month later. At Boston College, he played in 11 games and recorded 22 tackles for 218 yards and four touchdowns.
Rookie cornerback Dimitri Patterson appears to have earned a spot on the 53-man roster for the time being. Patterson had been on the Redskins' practice squad most of the season, but he was promoted last Saturday due to injuries to Carlos Rogers, Shawn Springs and Walt Harris.
Patterson recorded an interception on the last play of Sunday's win over Dallas, but otherwise saw limited action.

Both Joe Gibbs and New York Giants head coach Tom Coughlin are in their second seasons as coaches of their respective franchises. Both have their teams vying for the postseason.
It's the second time Gibbs and Coughlin have accomplished that feat with a team.
In Gibbs's first stint in Washington from 1981-1993, he guided the Redskins to a Super Bowl championship in his second season. As head coach of Jacksonville from 1995-2002, Coughlin led the Jaguars to the AFC Championship game in his second season.
This year, Gibbs has the Redskins at 8-6 and in the playoff hunt, while Coughlin has the Giants at the top of the NFC East with a 10-4 record. The Redskins and Giants square off in pivotal division game this Saturday at FedExField.
Asked about the Giants' turnaround, Coughlin said on Tuesday: "I don't believe it's a coincidence that it's happened. It's an entire team working together, focusing on priorities.
"It's an opportunity for people to get to know one another and share common values about the importance of winning--the values that allow you to succeed in this business and win."
