Background
For the first time in UFC history, all five fights on the main card will be Heavyweight bouts.
UFC Primetime will return to promote the main event.
Evan Dunham was expected to face Edson Barboza at the event. However, Dunham was forced from the event with an injury and replaced by returning veteran Jamie Varner.
Mark Hunt was originally scheduled to face Stefan Struve on the main card. However, on May 17, 2012, Hunt withdrew from the bout due to injury and was replaced by Lavar Johnson.
Alistair Overeem removal and card changes
Originally scheduled to headline the event was a Heavyweight Championship bout between one of UFC's newest stars, Alistair Overeem (who defeated former champion Brock Lesnar in his UFC debut to earn the title shot), and champion Junior dos Santos. On April 4, 2012, however, the Nevada State Athletic Commission (NSAC) announced Overeem had failed his pre-fight drug test. Overeem's March drug test showed a 14:1 testosterone-epitestosterone ratio, according to the NSAC.
This resulted in a considerable shake up of the matches on the main card. On April 20, 2012, UFC President Dana White announced that Junior dos Santos will now defend his title against Frank Mir instead. Two days later, White announced Cain Velasquez (who was originally slated to fight Mir in the co-main event) will now face Antonio Silva.. Roy Nelson (who was originally scheduled to fight Silva, and then briefly Gabriel Gonzaga) will face Dave Herman. And Shane del Rosario (who was originally slated to fight Gonzaga) will now face Stipe Miočić.
