Kansas City Chiefs quarterback Patrick Mahomes suffered a right patellar (kneecap) dislocation in the second quarter of Thursday night’s road win over the Denver Broncos, confirming multiple reports.  Mahomes will undergo an MRI to determine whether there is any ligament damage.

The NFL’s reigning MVP was injured on a quarterback sneak on fourth down with just over nine minutes remaining in the first half. As medical staff attended to him on the field, it appeared Mahomes’ knee was straightened and popped back into place.

A cart came onto the field, apparently to take Mahomes for treatment. He was instead helped off the field by a couple of trainers. Players from both teams came by to offer encouragement.

Mahomes, 24, soon left for the locker room, walking under his own power but with a limp.  A source said the Chiefs “will not know more until the [MRI] images.” If there isn’t damage, the best-case timeline for Mahomes “would be around three weeks.”
