The divisive Irish superstar was pulled from the fight last week after refusing to travel from his training camp in Iceland to fulfil promotional requirements.
Diaz, who stunned the MMA world last month with his submission victory over the featherweight champ at UFC 196 last month, is still scheduled to fight on the main card. However, he revealed it’s all-or-nothing and if he doesn’t face the Irishman, he’s going to “go on vacation”.
Speaking at the kick-off press conference for UFC 200, he said: “I just came to fight Conor McGregor. I don’t really have too much interest in anybody else.
“I don’t have any interest in fighting at all. But if that’s what we’re going to do, we’re going to do it.
“I didn’t ask for that fight, but he asked for it and he wanted it. If that ain’t gonna happen, I’m going on vacation for real.”
UFC president Dana White spent the majority of the press conference defending his decision to pull McGregor from the historic event at the new T-Mobile arena. He went on to explain that he “doesn’t see how it would be fair” for the Dublin native to fight at the event without attending press events.
And with McGregor’s absence, Frankie Edgar, who fights Jose Aldo on the mega card for the interim featherweight strap, called for their rematch to be bumped up for the undisputed title.
“I don’t know what’s going on in his head. I don’t really care, you know?” Edgar said of McGregor. “I think this fight should be for the vacant title right now, to be honest.
“I don’t think he’s ever coming down to 145lbs, if he ever even comes back. So I think me and Aldo should go at it for the real one.”
