The Thursday injury report for the Pittsburgh Steelers is now out and it includes some great news as linebacker James Harrison (knee) practiced fully for a second straight day. Harrison had not been able to string together two full practices all season up until this point and now it looks all but certain that he will make his season debut Sunday at Heinz Field against the Philadelphia Eagles.
Harrison missed all of training camp and the preseason with a left knee problem that ultimately required him to undergo a minor surgical procedure back in mid August. While the linebacker was able to work fully a few times in practice since that procedure was done, the knee never responded well enough for him to practice fully two days in a row, and thus he has not suited up at all this season.
Also practicing fully once again on Thursday were safety Troy Polamalu (calf), running back Rashard Mendenhall (knee) and tackle Marcus Gilbert (groin). Polamalu has missed the last two games with a strained calf, while Mendenhall looks to make his season debut after tearing his right ACL in the 2011 regular season finale.
