UFC star Conor McGregor vows to face Michael Chandler this summer - ESPN

Conor McGregor could be making a return to the Octagon relatively soon after his feature-film debut.

The former UFC double champion and biggest star in the history of the sport told ESPN on Tuesday that he will be coming back to fighting this summer, against Michael Chandler. The actual date and event are not yet known.

«We got confirmation a few days ago that it's all systems go,» said McGregor, who is promoting his first acting role in the movie «Road House,» which premieres March 21 on Amazon Prime. «And 'The Mac,' 'The Notorious' will be returning to the UFC Octagon this summer.»

The UFC has yet to officially announce McGregor's return. McGregor vs. Chandler has long been the plan, since last year when they coached opposite each other on The Ultimate Fighter reality show. McGregor previously said the bout would be June 29 at UFC 303.

Chandler has been calling McGregor out publicly often, including on an episode of WWE's «Monday Night Raw» last month. The UFC and WWE are sister companies under the publicly traded banner of TKO Group, owned by Hollywood media agency Endeavor.

«Shut up, Michael, you f---ing imbecile,» McGregor said. «The man doesn't shut up. I seen him on 'Raw.' I like Mike — I'm going to bust him up. I'm going to bust Mike up, yeah? If I say it, I do it.… If I say it, it gets done. Put that on my stone.»

McGregor originally said in January that the fight would be at 185 pounds. He has fought most of his career at 145, 155 and 170 pounds. McGregor said Tuesday that he was having a bit of fun with Chandler regarding the weight and he's not sure what weight class the bout will ultimately take place in.

Regardless, McGregor said he's happy that there is something he can begin training for again, in
