The Thursday injury report for the Pittsburgh Steelers is now out and it shows that tackle Mike Adams (back), linebacker James Harrison (knee), quarterback Byron Leftwich (illness), tight end Heath Miller (abdomen) and safety Troy Polamalu (calf) all failed to practice. Adams had been limited on Wednesday and Leftwich was added to the report today with an illness.
Running back Jonathan Dwyer (toe), tackle Marcus Gilbert (groin), wide receiver Emmanuel Sanders (knee) and wide receiver Mike Wallace (groin) all practiced fully on Thursday after sitting out Wednesday.
Running back Rashard Mendenhall (knee) and linebacker Stevenson Sylvester (knee) both practiced fully on Thursday. Sylvester was listed as limited on Wednesday, so signs are that he is getting close to returning to action.
At this point, Miller and Adams are the biggest concerns heading into Friday. The Steelers tight end reportedly suffered a rib cartilage separation in the game this past Sunday and has been sore ever since.
Both Harrison and Polamalu are not expected to play Sunday against the Oakland Raiders.
