Williams was waived by the Bills on Sunday, Ian Rapoport of NFL Network reports.
This might be the biggest surprise of cutdown weekend, considering Williams was expected to enter Week 1 operating as the top backup to LeSean McCoy. The 2016 fifth-round pick was limited to 27 carries for 94 yards in 11 games as a rookie, but he impressed this preseason with 21 carries for 121 yards. The Bills may feel comfortable with Mike Tolbert and Joe Banyard behind McCoy, or perhaps the team has another move in the works to acquire a replacement running back.
