The Buffalo Bills are down to their fourth-string running back as Marcus Murphy has left the game with what looks like a broken arm. He left the game in the second quarter and his return is officially “doubtful”.
Murphy was the starting running back after LeSean McCoy and Chris Ivory were declared inactive with hamstring and shoulder injuries, respectively.
Undrafted rookie Keith Ford was promoted from the practice squad this week and is the only other running back on the roster. Patrick DiMarco is still healthy at fullback and could give Ford a breather here or there.
