UFC held its 25th anniversary quarterly press conference on Friday in Los Angeles leading into the UFC 227 event set to take place this weekend in the Staples Center. Going into the festivities, the assumption was that the sole focus would be on the return of Nate Diaz to the Octagon after over two years away, as he's set to take on Dustin Poirier in the UFC 230 co-main event in Madison Square Garden on Nov. 3. That was until UFC president Dana White revealed the mega-surprise of the afternoon: Conor McGregor vs. Khabib Nurmagomedov for the lightweight title booked as the main event for UFC 229 on Oct. 6 in Las Vegas. 

Well Diaz, the biggest rival of McGregor's career, was none too pleased regarding the lightweight title bout announcement. 

Shortly after the announcement was made, Diaz could be seen storming off the stage from the press conference in Los Angeles. 

After Diaz vacated the presser, he took to Twitter to proclaim he's seemingly changed his mind about making his long-awaited return.

To add fuel to the fire, Diaz's scheduled opponent at UFC 230, Dustin Poirier, also hit the internet to express the similar sentiment of not taking part in the fight. Although, Poirier may have been just playing the part of a troll following the proclamation from Diaz. 

But things appear to be a little more clear after Diaz was found outside the press conference. Diaz says that White did not have his back while he was battling a lawsuit from his 2016 fight with McGregor. Diaz vented his frustration that White supported McGregor while the Irishman was going through a similar circumstance with Showtime and Mayweather, but that White didn't give him the same support in public and also claimed that Diaz was turning down fights.

"That's what I'm saying about the under promotion from this company. They're bad mouthing me, saying I turned down fights. I've never turned down a fight in my life," Diaz said.

Diaz also said that he was originally offered a fight against welterweight champion Tyron Woodley while still fighting his lawsuit, which he claims was settled a month ago.

When asked about McGregor during the press conference, Diaz shrugged the subject off, reiterating that he's defeated the Irishman twice already (still believing he should have earned the decision in their UFC 202 bout that resulted in a majority decision). But judging from the reactions here, McGregor still knows how to push Diaz's buttons -- even if he's not in the same building.
