Kansas City Chiefs quarterback Patrick Mahomes left in the second quarter of Thursday’s game against the Denver Broncos with what appeared to be a serious knee injury.

Immediately after he exited, videos surfaced that showed the extent of the injury. If you’re eating, we recommend putting the food aside or not watching this video.

As you can tell, the doctor popped Mahomes’ knee cap back into place. That’s never a good sign. It’s absolutely bone chilling in the worst possible way.

A former team doctor for the Washington Redskins hinted at what could be a season-ending injury for Mahomes.

This is just some horrible stuff.

Mahomes will obviously get further tests before a final conclusion is made. For now, it does not look good.
