UCF QB McKenzie Milton suffered one of the worst injuries you’ll ever see on a football field on Friday afternoon, dislocating his knee.

That required a quick trip to the hospital, where Milton had emergency surgery, likely to restore blood flow to his leg to try to save his leg.

While we await more news on the star quarterback, longtime NFL doctor David J. Chao shared his thoughts on the injury via Twitter:

Obviously, this is a terrifying situation for Milton and the UCF family. No matter who you root for, you never want to see guys go down like this.

Hopefully, Milton is eventually able to return to full strength and get back on the football field, but for now, the focus is on saving his leg, which is very scary.
