The Washington Redskins have signed right tackle Sean Locklear, a free agent, who last season started 15 out of 16 games for the Seattle Seahawks.

Locklear, a 6-foot-4, 310-pound eighth-year pro, arrived at Redskins Park on Thursday night and signed his deal Friday afternoon.

“It’s a good opportunity,” Locklear said. “I’m glad to be here. It’s a chance to come in, compete and see what happens. I was excited. It’s a chance to come back to the east coast. I’ve been in Seattle my whole seven years, so now to be able to come back East.”

The 30-year-old North Carolina State product entered the league as a guard, and in 2005 made the switch to tackle. Locklear has started 51 out of 54 games for Seattle since 2007.

It’s not immediately clear if Locklear will be used to back up right tackle Jammal Brown or left tackle Trent Williams. But it's possible that he could be used as both.

"They really haven’t said. I talked to coach Shanahan and he just said come in and compete. So we’ll see,” said Locklear, who said he feels more comfortable playing on the right side than left. “I’m just glad to be on the team. I’ll let them figure out where they want to place me.”

Locklear is the second veteran free agent lineman that the Redskins have added since training camp began. Washington last week added right guard Chris Chester, a free agent who last played for Baltimore. Chester began practicing with the team on Thursday and is projected to start at right guard.

Depth is an issue along the offensive line for Washington. Aside from 10th-year veteran guard/tackle Artis Hicks, Washington doesn’t have a veteran backup lineman. Selvish Capers, Xavier Folton, Erik Cook, Clint Oldenburg all are in their second or third seasons and have spent the bulk of their young careers on practice squads. Washington in April drafted Maurice Hurt, a seventh-round pick out of Florida.
