4. Jon Jones UFC 158
This was goddamn gruesome. At UFC 159 Jones defeated Chael Sonnen by TKO at 4:33 of the 1st round. Had Chael just made it to the 2nd round however, he might of had a chance to beat Jones because the champion had just badly messed up his toe.
It wouldn’t become known until after the fight was over however that Jones’ toe was a gnarly mess, and would evidently prevent him from going on his post-fight vacation in Jamaica. The pain was enough for Jones that he would have to sit down throughout his post-fight interview with Joe Rogan.
