Tyrann Mathieu likely has torn ACL, will have MRI to confirm

Tyrann Mathieu is feared to have a torn ACL in his left knee, Arizona Cardinals coach Bruce Arians said on Sunday.

Mathieu injured his knee on a kick return following a safety against the St. Louis Rams that made the score 23-3. Arians said in his postgame press conference that the Cardinals think it’s an ACL injury. NFL Network’s Ian Rapoport reported the same and says Mathieu will have an MRI on Monday to confirm what they think.

Mathieu slipped to the third-round of the NFL draft because of character concerns, but he has been spectacular for the Cardinals. He entered Sunday’s game with 67 tackles, a sack, two interceptions, a forced fumble and eight passes defended this season. He also had this awesome hustle play in his season debut.
