ケイン・ヴェラスケス
The event was expected to be headlined by a UFC Heavyweight Championship bout between the current champion Cain Velasquez and top contender Fabrício Werdum. However, on October 21, it was announced that Velasquez was forced to pull out of the bout due to an injured knee and was replaced by Mark Hunt. That also changed the originally planned title fight into an interim title bout.
