Su'a-Filo (knee) is not playing Sunday against the Steelers, Marisa Contipelli of the Bengals' official site reports.
Su'a-Filo picked up a leg injury in Week 2 against the Bears, and as expected, he wasn't able to recover in time to feature in this divisional matchup. As a result, Jackson Carman is likely to play a bigger role in this game.
