Pittsburgh Steelers inside linebacker Kwon Alexander suffered a leg injury in the first quarter of the game against the Green Bay Packers. Alexander had taken over the communication duties from Cole Holcomb, who had a season-ending knee injury the previous week. Alexander has been a key player in the Steelers' linebacker corps, with 41 combined tackles, five tackles for loss, one forced fumble, and an interception this season. With both Holcomb and Alexander out, Mark Robinson is getting an extended opportunity to play alongside Elandon Roberts.
