The Steelers placed Ekuale (knee) on injured reserve Friday.
Ekuale's season is over after he suffered a torn ACL in last Sunday night's loss to the Packers. Keeanu Benton and Yahya Black will see the bulk of the nose-tackle snaps for Pittsburgh. Prior to his injury, Ekuale logged six tackles (four solo) and one pass breakup on 14 percent of the Steelers' defensive snaps.
