The Buffalo Bills wrapped up their 2015 class of undrafted free agents by announcing the signings of 13 players Monday.
Offensive tackle Jermaine Barton of Illinois State and defensive end Erik Williams of Bethune-Cookman joined 11 other players reported Sunday by The Buffalo News and various other outlets.
Barton, a 6-foot-7, 315-pounder, started all 39 career games for the Redbirds, including 15 at right tackle in 2014. He was a third-team All-American.
Williams, the son of 11-year NFL veteran Lee Williams, played in 35 games for Bethune-Cookman. The 6-3, 270-pounder made 56 tackles, including 28.5 for losses, 10.5 sacks, three fumble recoveries and an interception in his college career.
Combined with the signing of defensive lineman Alex Carrington on Monday, the 13 undrafted free agents brings the Bills up to the roster maximum of 90 players. Should they want to sign anyone else in free agency, somebody would have to be released.
The rest of the Bills' undrafted free agent class, which was detailed in Monday's Buffalo News, includes: South Florida wide receiver Andre Davis, Florida tight end Clay Burton, N.C. State offensive tackle Tyson Chandler, Western Kentucky cornerback Cam Thomas, Wake Forest cornerback Merrill Noel, Stanford linebacker A.J. Tarpley, Washington linebacker Andrew Hudson, Louisiana-Lafayette defensive tackle Justin Hamilton, Utah State defensive end B.J. Larsen, Texas defensive end Cedric Reed and Baylor punter Spencer Roth.
