Steelers S Polamalu sits out practice (AP) (sports.yahoo.com)

Steelers safety Troy Polamalu didn't practice for the second straight day while he heals from a left knee injury. Polamalu is not believed to have had a setback in his rehabilitation, and he's expected to play Sunday against Minnesota as long as he practices Friday. Normally, the Steelers require a player to practice only once in advance of a game.
