The Bills waived wide receiver Cordell Roberson and cornerback Darius Robinson on Friday, the club said.
Buffalo did not immediately sign anyone to fill the vacated roster spots, leaving the club with 88 players, two short of the 90-player limit.
Roberson (6-4, 205) spent time on Buffalo and Carolina’s practice squads last season. The Bills placed him on their 53-player roster for the final game of the season. A Stephen F. Austin product, the 23-year-old Roberson signed with Cleveland after the 2013 draft.
Robinson (5-10, 175) signed with Buffalo as an undrafted free agent in May. Robinson, 22, played collegiately at Clemson.
