Pittsburgh Steelers running backs Rashard Mendenhall and Jonathan Dwyer are both listed as doubtful for Sunday's game against the New York Giants.
Mendenhall has appeared in just two games this season due to ACL surgery in the offseason and an Achilles injury suffered in Week 6, recording 74 yards on 19 carries while adding 44 yards on four receptions.
Dwyer and Isaac Redman, who is listed as probable for Sunday's contest after missing the last two games with an ankle injury, have carried the load for Pittsburgh in Mendenhall's absence.
Dwyer is coming of back-to-back 100-yard rushing games and has 299 yards on 58 rushes over five games this season, while Redman has 127 yards on 50 carries in five games.
In other injury news, safety Ryan Clark (concussion), running back Baron Batch (shin) and linebacker Brandon Johnson (hamstring) are also listed as probable for Sunday.
Safety Troy Polamalu (calf), offensive tackle Marcus Gilbert (ankle) and linebacker Stevenson Sylvester (hamstring) have all been ruled out of the contest.
