UFC 151

On August 23, Dana White announced that Henderson had sustained a partial rupture of his MCL and had withdrawn from the fight. White then announced via press conference that UFC 151 would be the first event in the organization's history to be cancelled, after Jones declined to fight Chael Sonnen, who agreed to take the fight on eight days' notice. Initially, White announced that Jones would defend his title against Lyoto Machida at UFC 152 and that UFC 151 simply would not take place.[5] Later, it emerged that Machida declined to fight Jones on such short notice. The UFC announced that former UFC Light Heavyweight Champion Vitor Belfort would challenge Jon Jones at UFC 152.[6]

Initial reports indicated that UFC 152, scheduled to take place three weeks later, would be renamed UFC 151. However, Zuffa announced that UFC 152 would keep its name and UFC 151 would officially be deemed a "lost show".[7] UFC middleweight champion at the time, Anderson Silva reportedly offered to save the event by fighting any light heavyweight other than Jon Jones,[8] and UFC middleweight contender at the time Chris Weidman also inquired about fighting Jones,[9] but both offers arrived too late, after cancellation processes began.

Dana White blamed the cancellation on Jones and his coach Greg Jackson, who advised him that accepting the fight with Sonnen on short notice would be the "biggest mistake of [his] entire career".[10] However, some MMA analysts see the UFC at fault for promoting thin cards.[11] With fights occurring nearly every weekend, the pool of fighters available as substitutes when injuries occur is shallow.[12][13] CBS Sports columnist Gregg Doyel argued Dana White's mishandling of UFC 151 proved that UFC competitors need a union, stating: "...fights fall through all the time – the flimsy card fell apart. This was the UFC's fault. This was UFC president Dana White's fault."[14] Dan Henderson was also criticized when it later emerged that he had been injured three weeks prior to the announcement and kept quiet about it as he still hoped to compete.[15]
