Wynn signed a two-year, $2.2 million contract with the Bills on Saturday, Joe Buscaglia of WGR 550 AM reports. Wynn served as a backup behind Mario Williams and Jerry Hughes last season, a role he'll fill once again in 2015 after the club re-signed Hughes on a five-year deal earlier in the week. In 11 games, Wynn recorded 17 tackles and two sacks.
