UFC heavyweight title fights don’t get any bigger than this.

The promotion today announced that Stipe Miocic will defend his crown against light heavyweight champion Daniel Cormier at UFC 226. The superfight will serve as the culmination of the two men coaching against each other on Season 27 of “The Ultimate Fighter.”

UFC 226 takes place July 7 at T-Mobile Arena in Las Vegas and airs on pay-per-view following prelims on FS1 and UFC Fight Pass.

Miocic (18-2 MMA, 12-2 UFC) and Cormier  (20-1 MMA, 9-1 UFC) both are coming off dominant title defenses last weekend at UFC 220. Miocic dismantled heavily hyped contender Francis Ngannou for 25 minutes to score a lopsided unanimous-decision win. Cormier, meanwhile, finished Volkan Oezdemir for a second-round TKO.

Not long after the event, UFC President Dana White lobbied for the superfight to happen between the two champions. Cormier’s main concern was the looming return of his American Kickboxing Academy training partner, former heavyweight champion Cain Velasquez.

“I don’t see why he couldn’t fight at heavyweight,” White said of Cormier after UFC 220. “If he thinks Cain might come back, then if he won the belt he could give it up. But either way, it’s a good fight. With all the defenses he has, Stipe just broke the record for most defenses, so it’s a fun fight.”

It will be the first time in UFC history that the acting 205-pound champion will challenge for the heavyweight title.

With his win over Ngannouo, Miocic set the record for most consecutive heavyweight title defenses at three. Afterward, he declared himself the greatest heavyweight of all time.

Cormier is no stranger to the division. He spent the first four years of his career competing at heavyweight and was the winner of the now-defunct Stikeforce Heavyweight Grand Prix in 2012. Cormier holds wins over heavyweight notables such as Frank Mir, Roy Nelson and Josh Barnett.
