The Buffalo Bills released S Mana Silva on Friday, according to the NFL transactions release.
Silva, 25, signed with the Ravens as an undrafted free agent out of Hawaii back in 2011. He was released before the start of the 2011 season and would later catch on with the Bills and Cowboys.
Last year, the Bills placed Silva on the reserve/left squad list where he remained for the entire season.
He has appeared in 12 games over the course of two season.
