Bam Knight Injury: Shut down for season

The Cardinals placed Knight (ankle) on injured reserve Tuesday, Zach Gershman of the team's official site reports.

Knight played just one snap in Sunday's 40-20 loss to the Texans before exiting the contest with a left ankle sprain. While follow-up tests revealed no structural damage, his sprain is significant enough to sideline him for the final three games of the season. With Knight joining James Conner (foot) and Trey Benson (knee) on injured reserve, Arizona will be left with Michael Carter and Emari Demercado as its primary backfield options. Knight will be a restricted free agent this offseason after he gained 269 yards on 82 carries (3.3 YPC) and four touchdowns to go with 160 yards and another score on 22 catches over 12 appearances for Arizona.
