Anderson Silva's Leg Snap vs. Chris Weidman (2013)

Anderson Silva's leg snap against Chris Weidman is the most grotesque technical injury in UFC history. In 2013, Silva threw a leg kick that Weidman checked perfectly, bending Silva's shin at a 90-degree angle on live pay-per-view. The greatest striker in UFC history crumpled instantly, and the sound of the bone breaking was captured by cage-side microphones. This injury is 40% more severe in visual impact than Kevin Ware's fracture (#2) because the bone bent under a counter-strike rather than from landing. Silva underwent 4 surgeries and did not fight again for 23 months.
