Polamalu has a calf injury suffered during the Steelers' Week 1 loss at Denver. Harrison had surgery on his knee Aug. 15, and did not play in the team's Week 1 game.
The Steelers will go with only seven offensive linemen for the second consecutive game. Right tackle Marcus Gilbert and right guard Ramon Foster were both injured in Week 1 and the Steelers played most of the second half without a back-up offensive lineman.
That's the lineup, kickoff is a little less than 30 minutes from the time of this post. It should be an outstanding game, so stick around BTSC for analysis and insight as the game starts at Heinz Field.
