Corto, 27, has been with the Bills in one form or another since entering the league in 2007 as an undrafted free agent out of Sacred Heart. He was re-signed to a two-year contract last year to play special teams for the Bills, but he was a rare part of the team's defensive plans, having not appeared there since Dick Jauron used him as a reserve linebacker earlier in his career.
Corto missed five games in 2010 with a wrist injury, then spent the entirety of the 2011 season on Injured Reserve. In a three-year span (2008-2010) in which he received playing time, Corto appeared in 43 games for the Bills, registering 37 tackles and a forced fumble as one of the team's go-to coverage specialists on kicks and punts.
Per the folks at Rotoworld.com, the Bills will be saving about $675,000 in salary by making this move.
