The Redskins have signed defensive lineman Jeremy Clark to their 53-man roster, the team announced on Thursday.
Clark takes the roster spot vacated by safety LaRon Landry, who was placed on injured reserve earlier this week.
The Redskins also signed rookie defensive lineman Joe Joseph to their practice squad this week.
Clark and Joseph provide some depth along the defensive line following the 4-game suspension of Albert Haynesworth last week.
Clark, 6-3 and 295 pounds, was most recently with the Dallas Cowboys from Nov. 10 to Dec. 12 earlier this year.
He spent training camp with the Arizona Cardinals but he was released at the end of preseason.
Clark entered the NFL as an undrafted rookie free agent with the Philadelphia Eagles on May 14, 2007. He spent his rookie season on the Eagles' practice squad.
A year later, Clark was on the New York Giants practice squad before being elevated to the active roster late in the season. He appeared in four games for the Giants, collecting three tackles.
He spent the 2009 season alternating between the Atlanta Falcons and Giants practice squads. He joined Arizona's roster for the postseason but was inactive for both of the Cardinals' games.
Clark played college football at Alabama, where he was a four-year starter at defensive tackle. He is a native of Daphne, Ala.
Joseph, 6-2 and 315 pounds, was originally signed by the Tennessee Titans as an undratfed rookie free agent on April 30, 2010.
He spent two weeks on the New York Giants practice squad earlier this month before being released on Dec. 14.
Joseph played college football at the University of Miami (Fla.), where he appeared in 37 games with 25 starts. He is a native of Orlando, Fla.
