Brazillian MMA fighter Marcos "Rino" Souza suffered one of the worst leg breaks ever and the result had to hurt both physically and psychologically.
Souza's leg snapped as he tried kicking opponent Cristian Goetz and after trying to take a step back, his leg buckled under the pressure. Slow motion shows it looks like the break happened more on the step-back than the kick and since there may be no way to really know, let's meet in the middle and saw this was horrific.
Because of the break mid-match, Souza also had to take a loss. That's definitely adding insult to injury. It also looks like he hasn't had a fight since.
