The Ravens signed veteran center Casey Rabach to a two year deal on Tuesday.  Rabach will likely take the starting role from the Ravens injured center Matt Birk, who reportedly may need arthoscopic knee surgery.  Birk needed to have his knees drained at least once week last season, but hasn’t missed a game since 2009.

Rabach rejoins the Ravens, the team that drafted him in the third round in 2001, after playing for the Redskins for the past six seasons.  He signed a three year, $12.3 million extension in 2010, but was cut before training camp as result of Washington deciding to go younger.

Rabach didn’t start in Baltimore, but filled in for the injured Matt Flynn in Baltimore in 2004.  After that season he left for Washington.
