Steelers center Pouncey dealing with injury
Steelers center Maurkice Pouncey was limited in practice Thursday because of an elbow injury, raising questions at a position where the Steelers are already short-handed. Pouncey, who has already battled ankle and knee injuries this season, was a full participant in practice Wednesday.
Doug Legursky, the Steelers' top backup at center, is already out for Sunday's game in Arizona with a dislocated toe. Trai Essex, who can play every position along the offensive line, is the No. 3 center.
Pouncey said after practice Thursday that he is OK, but the Steelers are only one injury away from having to use their third option at center.
"There would be a drop-off but not a drastic one," Steelers offensive coordinator Bruce Arians said when asked about Essex playing center. "He's had a ton of work at it, so he'd be solid."
> > Strong safety Troy Polamalu was a full participant in practice again Thursday. The 2010 NFL Defensive Player of the Year passed a concussion test earlier this week and is expected to play Sunday. Like Pouncey, running back Rashard Mendenhall appeared on Thursday's injury list after practicing fully Wednesday. Mendenhall was limited by a knee injury. Wide receiver Mike Wallace (hamstring) and outside linebacker Jason Worilds (quadricep) were also limited.Worilds said he suffered a bruise from a collision in practice but added that he should be OK. He is expected to play Sunday.
