Monday update: The Buffalo Bills will be without running back Zack Moss as they make their playoff run, per Ian Rapoport. Moss has been working as the Bills No. 1 running back, but now Devin Singletary will get the job back moving forward.
UPDATE: Moss suffered an ankle injury that could keep him out for the rest of the season, per Mike Garafolo.
UPDATE: Moss is officially doubtful to return with an ankle injury, per Chris Brown.
Buffalo Bills running back Zack Moss was injured early in the fourth quarter as the Bills drove over the 50-yard line up 17-10. Moss looked like he might have fumbled, but on review, he was down before the ball came out. The cart has come out for Moss, and he appears to be in real pain. Devin Singletary will likely finish this game out as the main running back.
