Fight week in Las Vegas has been as hot as the Nevada sun as the stars of UFC 279 have gotten up close and personal ahead of time in the lead-up to fight night in Sin City.

Order had to be restored during the pre-fight press conference, as a backstage melee forced the event to be scrapped, with UFC president Dana White commenting that the scenes were unlike anything he had experienced in more than 20 years of running the organisation.

Now, after a very eventful early morning weigh-in session, that resulted in the top three bouts on the card being completely remade, the fighters will face off for the final time as they take to the stage in front of a crowd packed with Las Vegas fight fans for the ceremonial weigh-ins.
