Conor McGregor says the fight with Dustin Poirier is off after the two exchanged words via Twitter on Monday.
The two stars are scheduled to face off at UFC 264 on July 10.
The chatter started when Poirier called McGregor out for not donating $500,000 to his charity, The Good Fight Foundation, after McGregor said he would if Poirier defeated him in January — which he did.
Poirier Tweeted that McGregor's team stopped responding when he inquired about the donation after the January fight. He said his foundation reached out three times with no reply and McGregor responded.
