The Redskins have signed linebacker David Holloway and waived linebacker Rian Wallace, the team announced on Monday.
Holloway, 6-2 and 230 pounds, spent time on the Arizona Cardinals practice squad last season.
He signed with the Cardinals' active roster for Arizona's season finale, but he was inactive for the contest.
Holloway visited Redskins Park in April 2007 as part of a pre-draft local college workout. He later signed with Arizona as an undrafted rookie free agent.
Holloway started 34 of the final 35 games of his college career at Maryland, playing both inside and outside linebacker.
The Stephentown, N.Y., native was born on Dec. 4, 1983. His father is former three-time Pro Bowl tackle Brian Holloway, who spent eight years in the NFL with New England and the Los Angeles Raiders.
Wallace spent all offseason and training camp with the Redskins, but he had difficulty staying healthy.
He was slowed by a fractured hand early in training camp. In last Saturday's preseason game against the New York Jets, he suffered a dislocated shoulder injury.
Wallace, a third-year pro out of Temple, was waived with an injury settlement.
