"The Washington Redskins have signed offensive tackle Cole Pemberton to their practice squad, a person with knowledge of the situation confirmed Tuesday afternoon.

The 6-foot-7, 308-pound Pemberton played college ball at Colorado State but went undrafted in 2010. He signed with the Houston Texans in January of 2011, but didn't appear in a game for the Texans this season.

The Redskins are looking for help along the offensive line with left tackle Trent Williams expected to miss the remainder of the season while serving a suspension for failing multiple drug tests."
