Steelers' Ladarius Green (concussion), Sammie Coates (hamstring) doubtful for Sunday

PITTSBURGH -- Pittsburgh Steelers tight end Ladarius Green (concussion) and wide receiver Sammie Coates (hamstring) are listed as doubtful for Sunday's game against the Baltimore Ravens.

Four key players are questionable, including defensive end Stephon Tuitt (knee), defensive end Ricardo Mathews (ankle), wide receiver Darrius Heyward-Bey (foot) and linebacker Anthony Chickillo (ankle).

Coates got hurt in practice this week, and the Steelers want to give him the weekend to see if his ailment lessens. Green, who has 274 yards in his last four games, did not practice all week after taking a shot in the back by Bengals linebacker Vontaze Burfict in Week 15.

Tight end Jesse James, who is fourth on the team with 33 receptions, said he expects to start in Green's place.

If Coates and Heyward-Bey miss the game, that leaves Antonio Brown, Eli Rogers, Cobi Hamilton and Demarcus Ayers as the only eligible receivers on the 53-man roster. The Steelers have three healthy defensive linemen if Tuitt and Mathews get ruled out.

Sunday's game will likely decide the AFC North division. Pittsburgh (9-5) has one game on Baltimore (8-6) but the Ravens own the tiebreaker.
