Tomlin also indicated that running back Rashard Mendenhall (knee) could be back on the field Sunday, the Pittsburgh Post-Gazette reported. Mendenhall has not played this season after suffering an ACL tear last year.
Harrison (knee) went through a full practice Monday. He did so last Tuesday but had a "little setback" and skipped Wednesday's practice. He has not played yet this season.
Polamalu (calf) went through a third straight practice Monday after missing the past two games.
Tomlin anticipates that Mendenhall will practice this week but didn't say whether he'd start or how much playing time he would get Sunday. The Steelers have used Isaac Redman and Jonathan Dwyer in the backfield.
