Why do you wink with your ears? You fucking brain dead hillbilly. 500k with no plan in place. Ye hang tight. Fool. You must be new to money. The fight is off btw. I’m going to fight someone else on the 10th. Good luck on your old contract kid.— Conor McGregor (@TheNotoriousMMA) April 12, 2021But Dana White's most recent announcement surely puts a stop to all such speculation.The tumultuous exchange started when Conor McGregor predicted he would win the trilogy fight via a front kick to the nose of Dustin Poirier in the fourth round. Dustin Poirier took this opportunity to take a dig at Conor McGregor, claiming that he never sent the promised $500,000 donation to the former's Good Fight Foundation following their second fight.Dustin Poirier said that Conor McGregor's team never replied to their messages about the donation in the tweets that followed. At the same time, the Irishman claimed that he was never informed about the plans the Foundation had for the amount.100% never a debt. You offered, we accepted, and like I said your Team never responded to our emails regarding the process of where funds would be put to work! July 10th you will taste defeat yet Again https://t.co/k3Cu9DG1Me— The Diamond (@DustinPoirier) April 12, 2021However, with all that said and done, the fight is all set to happen and that too, with 20,000 fans in attendance.
