The Ravens signed offensive tackle Mark LeVoir and center Jason Murphy on Sunday morning. To make room for the new additions, the Ravens released guards Colin Madison and Kyle Calloway.

As mentioned yesterday, LeVoir joins the Ravens after being released from New England after he refused to take a pay cut for the 2011 season. Murphy comes with a little less experience than LeVoir, as he has spent time on the Titans, Seahawks and Chargers practice squads. Murphy is 6′ 2″, 310 pounds, 29 years old, a Baltimore native and a Virginia Tech alum.
