Nurmagomedov succeeded the Irishman as the title holder and the fight between the current champion and the old hero is scheduled to take place in Las Vegas on October 6th. Nurmagomedov (26-0) won the title in April at UFC 223 against last minute challenger Al Iaquinta in a dominating performance that ended with a unanimous decision.
Combat sports fans were expecting the UFC to organized a world tour to get McGregor and Nurmagomedov to promote their fight which is being billed as the biggest MMA fight in the history of the sport. Last month he was sentenced to five days of community service in the United States after pleading guilty to disorderly conduct.
The announcement was made at a UFC news conference to reveal fight cards running through the end of the year, including the November 3 co-main event between McGregor's heated lightweight rival Nate Diaz and gritty Dustin Poirier.
Nurmagomedov has been one of the pound-for-pound greats of MMA, racking up 10 consecutive victories since joining the UFC. But with McGregor back in the octagon, and his mouth back selling the fight, there's a good chance that the personal bad blood between these two fighters leads to one of the highest-selling PPVs the company has ever had.
As the former two-division UFC champion embarks on a tour of Australia this week, he spoke about his future after teasing his return to action earlier this year and hinting that he might be ready to fight again before the end of 2018.
The Ultimate Fighter victor added that he is not sure if he will fight at UFC 230.
McGregor has posted several photos on social media this week hyping his physical fitness in advance of the announcement, which neither fighter attended.
"It's time to go, so it's time to go", Diaz said. But it seems time and no lack of contrition from McGregor has softened the UFC president's stance as he told ESPN: "Conor came and did what he did and didn't expect the results that happened".
As it played, Diaz abruptly left the presser he was at and tweeted "I'm not fighting on that show (expletive) the UFC".
