17. Chris Weidman (2021)
Anderson Silva’s leg break against Weidman will always be one of the most notorious injuries in UFC history. Then, in a set of surreal circumstances, Weidman suffered a near-identical break against Uriah Hall. The injury was gruesome and difficult for fans to look at because of the angle of his leg. There’s clearly something horrible about bones pointing in the wrong direction.

Doctors informed Weidman that there was a genuine risk of infection spreading through his body. They told him that this was a serious health risk and there was a significant chance that amputation was necessary. In the end, it didn’t come to this and Weidman rehabbed the injury. There was still a long way to go and the injury is still career-threatening, but thankfully his life was secure.
