Karlos Williams is ready to roll in Buffalo.
The Bills announced that the second-year running back passed his physical and will participate in Monday's practice.
Williams is still facing a four-game ban to start the year for violating the NFL Policy and Program for Substances of Abuse. Williams started camp on the team's active/non-football illness list after showing up 20 pounds overweight. The power back acknowledged in June that he tacked on the extra heft while tending to -- and eating with -- his wife during her pregnancy. Although the team signed Reggie Bush, we still feel Williams is the back behind LeSean McCoy, assuming he's fully ready to go once his suspension is over. Mike Gillislee and Jonathan Williams are listed behind Williams but both could see work in Karlos Williams' absence.
