Polamalu officially is listed as questionable, and his status might be a game-time decision. Tomlin and the Steelers' medical staff want to see how Polamalu responds to Friday's practice before deciding whether or not he can play Sunday.
"It's 100 percent on what coach Tomlin decides," Polamalu said. "Right now (the Achilles) feels pretty good, so hopefully I don't have a setback."
"It would help me tremendously," Polamalu said of having a playoff bye week. "It would help a lot of guys on this team tremendously. There's guys that are just barely hanging on by a string, week by week. Unfortunately for me, that string broke, and it's time for me to tie it back up there again."
Running back Mewelde Moore (knee) and defensive end Aaron Smith (triceps) will sit out Sunday. Linebacker Jason Worilds (knee) is questionable.
