At the end of a week in which he had confronted another fighter at the UFC Performance Institute and later caused the cancellation of the pre-fight press conference by starting a series of backstage incidents, Khamzat Chimaev missed weight for his main event against Nate Diaz.
As a result, the card has been reworked, with rising star Chimaev now facing Kevin Holland – with whom he engaged in one of Thursday’s backstage brawls – in a catchweight bout, while icon Diaz takes on fan favourite and fellow veteran Tony Ferguson in the new main event.
Meanwhile, Ferguson and Holland’s originally-scheduled opponents, Li Jingliang and Daniel Rodriguez, will fight one another in a catchweight contest.
