The Ravens signed former Redskins C Casey Rabach to a two-year deal on Tuesday.
Rabach, an 11-year veteran, began his career in Baltimore and played in 42 games for the Ravens from 2002-04 before joining the Redskins. He has missed one start in the past seven seasons.
The Redskins cut Rabach, who turns 34 in late September, last week. They also signed former Ravens OG-C Chris Chester.
Ravens C Matt Birk has been out early in training camp because of issues with his knee.
