Cardinals safety Tyrann Mathieu out for season with torn ACL
Monday December 21st, 2015

Arizona Cardinals safety Tyrann Mathieu is out for the rest of the season with a torn ACL injury, head coach Bruce Arians told reporters Monday. 

Mathieu exited Sunday's 40–17 win over the Philadelphia Eagles in the fourth quarter after sustaining the injury without much contract from an opponent. He underwent an MRI in Phoenix on Monday morning. 

Mathieu, 23, previously tore the ACL and MCL in his left knee as a rookie in 2013 and missed the final three games of the season. He returned last year to play in 13 games with six starts.

KING: Another Smashing Sunday

The former LSU Tiger has 89 combined tackles and five interceptions on the year.

The Cardinals will face the Green Bay Packers and the Seattle Seahawks for the final two games of the regular season.
