Woodley was downgraded to not practicing Wednesday after participating on a limited basis Tuesday. He hasn't played in the past two games due to the injury.
Ravens starting defensive end Chris Canty was limited in practice again Wednesday with a shoulder injury, but he's listed as probable and is expected to start. Rookie safety Brynden Trawick was ruled out due to a high-ankle sprain suffered Sunday against the New York Jets.
The Steelers previously ruled out starting nose tackle Steve McLendon with a sprained right ankle.
Several other Steelers players are listed as probable, including defensive end Brett Keisel (foot), who missed the past two games, linebacker Stevenson Sylvester (hamstring), safety Shamarko Thomas (ankle), tight end Heath Miller and safety Troy Polamalu.
