Gerry Dulac of the Pittsburgh Post-Gazette reported that Steelers running back Willie Parker didn't practice Wednesday and is now uncertain for Sunday's game. Dulac said Parker stepped in a hole in practice Monday and aggravated the sprained medial collateral ligament in his left knee that took him out of the previous two games. Parker has four 100-yard against the Bengals and has averaged 4.3 yards against them in his career.
