Dana White says he's yanked Conor McGregor from UFC 200 -- claiming the Irish superstar refused to fly to Vegas to promote the event.
McGregor tweeted about retiring earlier Tuesday -- clearly a reaction to whatever beef he was having with Dana behind the scenes.
"Conor did not want to come to Las Vegas and film the commercial or be a part of any of the marketing that we have," White told ESPN.
White noted McGregor is currently training in Iceland and refused to fly in for the press conference.
"You have to do the press conference," White said ... noting that he once pulled Nate Diaz's brother Nick Diaz from a fight when Nick blew off a presser.
We're told Conor is not begging Dana to reconsider ... sources connected to Conor tell us he has NOT called the UFC back after White made the decision and WON'T call back either.
As for Conor's future with the UFC, we're told he won't be suspended or penalized any more than this.
