You didn’t need to see Cardinals rookie Tyrann Mathieu go down to know it was bad.
Tests have confirmed it’s perhaps worse than it looked.
According to Ian Rapoport of the NFL Network, Mathieu tore both the ACL and the LCL in yesterday’s ugly collision.
Tearing multiple ligaments complicates any recovery, so it might not be as simple as assuming he’ll be well when the Cardinals start back next summer.
Mathieu was blossoming into a playmaker for the Cardinals, justifying the third-round draft pick, as be could play safety and cover slot receivers.
