Roethlisberger practices despite Sunday concussion
PITTSBURGH -- Steelers quarterback Ben Roethlisberger has practiced despite sustaining a concussion against Kansas City and is expected to play Sunday in Baltimore.
While Roethlisberger went through a usual Wednesday practice, second-year quarterback Dennis Dixon took more snaps than usual. Dixon moved up the depth chart when backup Charlie Batch broke his left wrist during the 27-24 loss to the Chiefs.
The Steelers added a third quarterback by signing former three-year Pitt starter Tyler Palko to their practice squad.
Defensive end Travis Kirschke practiced after missing three games with a torn left calf muscle. Safety Troy Polamalu (left knee ligament) missed the workout.
