Aaron Smith, Casey Hampton out

The Pittsburgh Steelers scratched six players for Sunday's game against the Tennessee Titans.

Ruled out are defensive end Aaron Smith (foot), defensive tackle Casey Hampton (shoulder), linebacker James Harrison (eye), linebacker Jason Worilds (quad), guard Chris Kemoeatu (knee) and halfback Mewelde Moore (ankle).

Halfback Rashard Mendenhall (hamstring) had a limited practice Friday and is questionable. He will be a game-time decision. Cornerback Cortez Allen is questionable with an ankle injury.
