The Pittsburgh Steelers will be without linebacker James Harrison and safety Troy Polamolu again this week due to injuries, according to ESPN's John Clayton.
Harrison has not played since Pittsburgh's playoff loss at Denver to close last season because of a knee problem that needed surgery during preseason.
Polamalu will miss his second straight game with a calf injury that has not responded well this week.
Running back Rashard Mendenhall, still trying to make his way back from a torn ACL last year, will miss his third straight game.
