The Washington Redskins have added tight end Dominique Byrd to the 53-man roster to fill the spot created when Chris Cooley was placed on injured reserve Tuesday.

Byrd, selected by the St. Louis Rams in the third round of the 2006 draft out of USC, appeared in 14 games and recorded a combined six catches for 83 yards and one touchdown in his first two seasons in the NFL. Byrd then spent the next two seasons in Arizona, but didn’t appear in a game. Most recently he was with the Seattle Seahawks, appearing in one game this season.

The 6-foot-3, 255-pounder likely will compete with Mike Sellers for playing time as the team’s third tight end.

Byrd joins fellow former USC tight end Fred Davis on the roster.

The Redskins also have added center/ guard Jonathan Compas to the 53-man roster.

The Cal- Davis product signed with Oakland as an undrafted rookie in 2009, and had brief stints with Tampa Bay and New England in the last year.

He played guard in college but learned how to play center once he reached the NFL.

Compas said he expects to be used at both spots by the Redskins.

“It’s a great opportunity. Just want to come in and help whatever way I can,” he said.

The Washington Redskins have signed running back Tristan Davis to their practice squad.

Davis, who played at Auburn but went undrafted in 2009, started this season on the Pittsburgh Steelers’ practice squad.

The 5-foot-10, 212-pound Davis previously had stints with the Detroit Lions and Miami Dolphins practice squads in 2009 and 2010, and was on Minnesota’s active roster for a portion of 2010, but never played in a game.

To make room for Davis on the practice squad, Washington cut John Malecki.

It’s unclear what this means for rookie Evan Royster, whom Washington drafted in the sixth-round out of Penn State. As of Wednesday morning, he remained on the team’s practice squad and hadn’t been promoted to the 53-man roster, according to a person familiar with the situation.

The Redskins currently have only Ryan Torain and Roy Helu as the running backs on their 53-man roster.
