PITTSBURGH -- Steelers outside linebacker Lawrence Timmons practiced Wednesday as he recovers from a high ankle sprain, but he didn't finish the workout.
The Steelers were hopeful that Timmons could play Sunday in Chicago, but the injury flare-up is a setback. Timmons originally was hurt during an Aug. 22 preseason game against the Washington Redskins.
Tyrone Carter, the veteran safety who will replace injured Pro Bowler Troy Polamalu, didn't practice for personal reasons.
