In a surprise move, the Buffalo Bills waived running back Jonathan Williams on Sunday, NFL Network reported.
Williams was expected to play a significant role behind LeSean McCoy in the Bills' backfield after Mike Gillislee signed a restricted free-agent deal with the New England Patriots in the offseason.
Without Williams, the Bills are now expected to use veteran Mike Tolbert as their top option behind McCoy. The team also kept running backs Joe Banyard and Taiwan Jones, whose main contributions are expected to come on special teams, on their 53-man roster.
