Patrick Mahomes injured in second quarter; will not return

UPDATE: 9:10 p.m. Arrowhead Time

Friend-of-the-site Terez Paylor of Yahoo! Sports is reporting early indications are that Patrick Mahomes has a “dislocated knee.”

NFL Network’s James Palmer confirmed Paylor’s thought.

Early in the second quarter of the game against the Denver Broncos on Thursday night, Kansas City Chiefs quarterback Patrick Mahomes was injured during a quarterback sneak on a fourth-and-1 play at the Broncos 5-yard line.

Mahomes was clearly in pain as the bodies were unpiled from the successful sneak, removing his helmet before trainers could arrive.

Trainers were clearly working on Mahomes’ right knee. It appeared that trainers attempted to relocate something — which caught the attention of our in-house medical expert Aaron Borgmann.

Mahomes was helped to the sideline and then went to the locker room under his own power after waving off a cart ride. Backup quarterback Matt Moore went into the game to finish the drive, which ended with a Chiefs field goal.

Mahomes received X-rays in the locker room. Shortly thereafter, the Chiefs announced he would not return to the game.

Naturally, there was immediately plenty of online speculation about the exact nature of Mahomes’ injury — and how long he might be sidelined.

Aaron Borgmann weighed in on that discussion, too.

So as much as we’d like for there to answers for all questions surrounding Mahomes’ injury, the earliest we could possibly know anything concrete is Friday — and it could take longer than that.
