After the 2011 NFL season labor dispute had ended, the Ravens had informed veterans Willis McGahee, Todd Heap, Kelly Gregg, and Derrick Mason that they would be cut in order to free up salary cap space. Following these cuts, the Ravens acquired fullback Vonta Leach, wide receiver Lee Evans, safety Bernard Pollard, and running back Ricky Williams. During the pre season, the Baltimore Ravens signed Left tackle Bryant McKinnie from the Minnesota Vikings. On top of that the Ravens signed Pro bowl center Andre Gurode from the Dallas Cowboys. With the new signings, there was a reshuffle within the Offensive line. The signing of McKinnie forced Michael Oher over to the Right Tackle position, which in turn allowed Marshall Yanda to revert to his natural Right Guard position. The Ravens finished their pre season 3–1, with a loss to the Philadelphia Eagles, and victories over the Washington Redskins, the Kansas City Chiefs, and the Atlanta Falcons.
