Conor McGregor’s press conference in Dublin, Ireland, was abruptly canceled but his fight against Michael Chandler at UFC 303 is still on, he says.

“In consultation with the UFC, todays press conference was canceled due to a series of obstacles outside of our control,” McGregor posted on X. “I apologize to my Irish fans, and fans around the world, for the inconvenience and appreciate all your passion and support. I can’t wait to put on the greatest all-time show in the Octagon.”

McGregor did not explain in more detail why the press conference was canceled with just 12 hours notice.

The UFC had previously said that it was looking to reschedule the press conference.

“The #UFC303 press conference scheduled for Monday June 3rd in Dublin, Ireland at 3Arena has been postponed until further notice,” the outfit said in a statement. “We sincerely apologize to all the fans who were planning to attend.  When we have further information on a new date and time, we will share it immediately. – Thank you.”

McGregor is slated to fight Michael Chandler on June 29, and the press conference was supposedly garnering so much attention that the tickets, which were free to the public, were even being sold on secondary ticket markets.
