Pittsburgh Steelers linebacker LaMarr Woodley and safety Troy Polamalu have been ruled out for Thursday's matchup against the Tennessee Titans.

Woodley missed practice all week with a hamstring injury he suffered in Pittsburgh's 16-14 triumph over the Philadelphia Eagles on Sunday.

Polamalu limped off the field during Sunday's victory after aggravating a right calf injury which forced him to miss the previous two games.

Linebacker James Harrison (knee) and running back Rashard Mendenhall (knee), who made their season debuts on Sunday, were limited in practice on Monday and Tuesday but participated fully in Wednesday's session and are listed as probable.
