UFC fan-favourite Nate Diaz brought the curtain down on his UFC career, for now, with a fourth-round submission of former interim lightweight champion Tony Ferguson at UFC 279.
After a turbulent two days in Las Vegas that saw a wild melee backstage at the pre-fight press conference on Thursday, and multiple fighters miss weight on Friday, the UFC has called an audible on its fight card to keep the event intact.
Drama reigned at the official early morning weigh-ins for UFC 279 as headliner Khamzat Chimaev missed weight by a colossal seven and a half pounds for his welterweight main event bout with Nate Diaz.
Fight week skirmishes between fighters are nothing new to the UFC, but even the famously well-drilled UFC staff were caught out when, in the moments in the immediate lead-up to the UFC 279 pre-fight press conference, all hell broke loose backstage.
Featherweight contender Josh Emmett edged one step closer to the top of the UFC 145-pound division with a hard-earned split-decision victory over fellow contender Calvin Kattar at UFC on ESPN 37.
The bad blood may live on, but bragging rights sit firmly with Colby Covington after the former interim welterweight champion dominated rival Jorge Masvidal in the main event of UFC 272.
