UFC president Dana White confirmed that there while there would be no World Tour for Khabib Nurmagomedov vs. Conor McGregor, we would see a couple of press conferences for the UFC 229 mega-fight. As of Wednesday, the first presser has been finalized.
The UFC announced that Nurmagomedov and McGregor will appear on stage at Radio City Music Hall in New York City on Thursday, September 20th. White is also going to be present, along with credentialed media, but the event is closed off to the public. Of note is that UFC 230 tickets for November 3rd go on sale to the public the following day, so we should have a main event announced for that card soon.
