Walter rushed 14 times for 49 yards and wasn't targeted in Sunday's 28-24 loss to Tampa Bay.
Walter led the team in carries after Michael Carter (concussion) exited early, but Ty Johnson got the nod at the goal line in the third quarter and delivered a one-yard touchdown. If neither Carter nor Tevin Coleman (illness) plays in Week 18 against the Bills, Walter should retain a prominent role on the ground, though finding running room won't be easy against a stout Buffalo front.
