The Redskins are expected to host free agent offensive tackle Donald Penn this weekend, a person with knowledge of the situation confirmed.

Washington’s efforts to improve the offensive line that will protect Robert Griffin III and pave the way for Pro Bowl running back Alfred Morris remain ongoing.

The Tampa Bay Buccaneers released Penn earlier this week. He has started 108 consecutive games dating from the 2007 season. He has spent the majority of his career at left tackle, but Washington has interest in acquiring him to play right tackle.

The 6-foot-5, 340-pound Utah State product made the Pro Bowl in 2010. Redskins general manager Bruce Allen held the same title in Tampa during a portion of Penn’s career there, and Redskins secondary coach Raheem Morris served as Penn’s head coach from 2009-11.

CBS Sports first reported that the Redskins were expected to host Penn and that the team also has begun the early stages of contract negotiations with his camp.
