UFC 151

[2] The fight between Thiago Tavares and Dennis Hallman was originally scheduled to take place at UFC 150, but was moved to this event on July 12, 2012.

[3] Josh Koscheck was expected to face Jake Ellenberger, but pulled out of the bout, citing a back injury and was replaced by returning veteran Jay Hieron.

[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".

"[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.
