Pittsburgh Steelers Pro Bowl outside linebacker James Harrison and safety Troy Polamalu will make their 2011 preseason debuts Thursday against the Philadelphia Eagles, Steelers head coach Mike Tomlin confirmed. Harrison is returning from offseason back surgery. Polamalu rested after last season's Achilles injury.
Pittsburgh's No. 1 cornerback, Ike Taylor, had successful thumb surgery and is expected to miss the rest of the preseason.
