The Ravens shored up their offensive line Sunday by signing offensive tackle Mark LeVoir and center Jason Murphy to the roster.
LeVoir is a five-year veteran who has spent the previous three seasons with the New England Patriots. The 6-foot-7, 310-pound LeVoir adds depth to a tackle position that has temporarily lost Oniel Cousins, who started at right guard in place of Marshal Yanda during the team's 31-13 victory over the Kansas City Chiefs Friday night.
Murphy, a Baltimore native and Edmondson graduate, has spent time on the practice squads of Tennessee Titans, Seattle Seahawks and San Diego Chargers. The 6-foot-2, 310-pound Murphy joins a group of centers that could be forced to play the entire preseason without starter Matt Birk (left knee surgery). Bryan Mattison has started the first two preseason contests at that position, and rookies Tim Barnes and Ryan Bartholomew have also occupied the spot.
To make room for LeVoir and Murphy, the Ravens waived guard/tackle Kyle Calloway and rookie guard Colin Madison.
