Orchard Park, NY (SportsNetwork.com) - The Buffalo Bills signed cornerback Corey Graham on Wednesday.
Graham, a 2011 Pro Bowl selection, recorded career-highs of four interceptions and 12 passes defensed to go along with 68 tackles with the Baltimore Ravens in 2012.
"Early in the free agent process, we identified Corey Graham as a player who could help our football team," Bills general manager Doug Whaley said. "Graham is a smart, physical and tough cornerback who has had success with both the Chicago Bears and Baltimore Ravens."
Graham spent his first five years in the NFL with the Bears before joining Baltimore in 2012.
In addition, the Bills signed offensive lineman Chris Williams and agreed to terms with linebacker Keith Rivers.
Williams started all 16 games for the Rams last season. The Louisiana native has participated in 69 contests (54 starts) over six NFL seasons with Chicago and St. Louis.
Rivers struck for 45 tackles and one sack in 16 games for the Giants in 2013. Heading into his sixth pro season, the Southern Cal product has totaled 275 tackles, three sacks and two interceptions in 62 games for Cincinnati and New York.
