"Bengals defensive end Carlos Dunlap did not practice on Wednesday and could miss playing against Pittsburgh for the second time this season because of a strained hamstring.

The Bengals (7-4) and Steelers (8-3) meet for the second time in four games Sunday at Heinz Field in Pittsburgh in a matchup that will have major implications on the playoff race in the AFC.
