It started with McGregor turning up around half an hour late, saying he believed the press conference was supposed to begin at 1.30 Vegas time. 

Diaz, Dana White, Anthony Johnson and Glover Teixeira had been answering press questions, when Diaz stormed off with his crew a few minutes after McGregor arrived and apparently threw the first bottle. 




 The fight takes place this Sunday morning on BT Sports. The main card begins at 3am, with McGregor and Diaz headlining as the last fight on the card.
