Buffalo Bills running back Karlos Williams has been released, the team announced Saturday.
The move comes after the second-year running back reported to spring and training camp overweight. He must also serve a four-game suspension for violating the NFL’s substance abuse policy before he can play in the regular season.
Williams was expected to be second running back on Buffalo’s depth chart behind LeSean McCoy this season. The Bills also have veteran Reggie Bush, Mike Mike Gillislee, James Wilder Jr. and rookie Jonathan Williams on the roster.
Williams played well as a rookie in 2015, rushing for 517 yards and seven touchdowns. His nine total touchdowns was tied for best on the team with receiver Sammy Watkins.
