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, a source told ESPN's Stephania Bell, confirming multiple reports.

Mahomes will undergo an MRI to determine whether there is any ligament damage, a source told ESPN's Adam Schefter.

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.

Veteran Matt Moore, who joined the Chiefs (5-2) late in the preseason after backup Chad Henne broke his right ankle, replaced Mahomes. He threw a 57-yard touchdown pass to Tyreek Hill and completed 10 of 19 passes for 117 yards.
