Tyrann Mathieu, the Cardinals’ talented rookie safety, injured his leg on a kick return during Sunday’s game with the Rams. The leg appeared to buckle when a Rams’ defender knocked into it. Mathieu, aka the Honey Badger, tried to walk off under his own power but crumpled to the field en route.

The Cardinals were much better than expected this season, and the defense was a major reason why. They should compete for a Wild Card spot again next season.]
Mathieu will have an MRI on Monday, but most are reporting the rookie likely tore his ACL:
