Lewis re-aggravated his hip injury last Sunday against the Dallas Cowboys, and the team listed his hip as the official reason that he was limited in Wednesday's practice. Dulac, however, reported that Lewis stepped in a hole during practice, which caused him to injure his knee.
The cornerback told the media before practice that he would play against the Cincinnati Bengals. Lewis is expected to draw A.J. Green if healthy, as Ike Taylor is still recovering from a fractured left ankle.
Sunday's game against the Bengals is an extremely important game for both team's playoff chances. If the Steelers win against the Bengals and next week against the Cleveland Browns, they are guaranteed a playoff spot, while a Cincinnati victory would eliminate Pittsburgh from the playoffs.
