TEMPE, Ariz. (AP) Safety Tyrann Mathieu, one of the inspirational leaders on the Arizona Cardinals defense, is out for the season with a torn ACL.
Coach Bruce Arians revealed the extent of the injury at his Monday news conference.
Mathieu injured his right knee after intercepting a pass in the final minutes of Sunday night's 40-17 victory at Philadelphia.
It's the second serious knee injury for Mathieu in his young career. He hurt his left knee in the 2013 season.
Mathieu, known to fans as the ''Honey Badger,'' was having an outstanding season and was the NFC defensive player of the month for November.
