The Buffalo Bills on Monday signed veteran safety James Ihedigbo, who has a familiarity with coach Rex Ryan's defensive system.
Ihedigbo played two seasons, 2009 and 2010, for the New York Jets when Ryan served as head coach. He played in 29 games over that span, all as a reserve.
The Bills have been searching for a starting safety opposite Corey Graham since Aaron Williams was placed on injured reserve Nov. 1. Veteran backup Robert Blanton has started the past two games in Williams' place.
