It's not a shock to learn safety Troy Polamalu and outside linebacker James Harrison will miss Sunday's game at Oakland. They've been ruled out of Sunday's Week 3 game at Oakland, as has linebacker Stevenson Sylvester and running back Rashard Mendenhall, but the Steelers will have Heath Miller in pads, despite only practicing Friday this week.

Miller is tied for the team lead with two touchdowns, and has been an instrumental part of the offense through two weeks.

Right tackle Marcus Gilbert, wide receivers Emmanuel Sanders and Mike Wallace and RB Jonathan Dwyer all practiced Friday and will likely play Sunday.

Mendenhall practiced fully all week and is likely being held out for precautionary reasons. The Steelers have a bye in Week 4, and host Philadelphia in Week 5.

It's likely Mendenhall will be back for Week 5, given the fact the Steelers removed Mendenhall from the PUP list, electing to keep him on the regular season roster. A decision to leave him on the PUP for the regular season would have kept him out of practice and games through the Steelers' first six games.

At the same time, the team has said Mendenhall will play when he's ready. Steelers coach Mike Tomlin said they were going to "thud him up a little bit" this week, and see how he responds. All indications suggest he survived said thudding, and could be available after the bye.
