#1 Mike Florio's leg
In November 2013, the Orleans Hotel and Casino played host to Tuff-N-Uff: Future Stars of MMA. One of the fights on that card was between Mike "The Jersey Devil" Florio and debutante Jim Elmer. In the first round, after a few exchanges, Elmer managed to pull Florio's legs out from under him and dump him on the floor.

What the crowd saw next is easily the most nauseating and gut-churning MMA injury of all time. Due to the force of the takedown, not only had Florio's leg broken, but his shin bone had pierced the skin and was visible. Neither man fought again after that terrifying experience. The picture below doesn't show Florio's whole body, just the leg, but its veracity is proven because it has the same doctor who's seen in the video.
