Cormier, the light heavyweight champion, is moving up to challenge the heavyweight champ for the possibility of following in the footsteps of Conor McGregor as the only fighters to simultaneously hold UFC belts in two weight classes.
Lesnar has mostly been an absent champion with WWE since winning the Universal title from Bill Goldberg at last year's WrestleMania.
Lesnar can not fight until at least January because of his suspension, while Cormier, 39, has set a firm retirement deadline of his 40th birthday on March 20.
UFC punished Lesnar by fining him $250,000 and suspending him for one year, which lead to Lesnar declaring his retirement from the sport.
After Cormier won, he set his sights on Lesnar and told him to come to the octagon. Clearly, there's a case to be made that Cormier can score the upset and beat Miocic, especially because he was previously undefeated at heavyweight before moving down to 205 lbs.in 2014.
The heavyweight title is on the line and below we discuss why the oddsmakers have it all wrong as Daniel Cormier is poised to capture his second divisional crown.
Following the altercation, UFC president Dana White confirmed that Cormier's first title defense will be against Lesnar - likely at Madison Square Garden in November.
For Miocic, a victory will extend his championship reign to five fights, the longest of any heavyweight champ in the UFC's history.
"Yeah, you're strong, but everybody's strong." an incensed Cormier said.
On Saturday, July 7, the UFC will host UFC 226 from the T-Mobile Arena in Las Vegas. "I went from that to become the heavyweight champion".
"It's weird", Cormier said.
"Him and Vince have a good relationship", White said. "They started the process last week".
In the beginning of 2018, the speculation in wrestling was Lesnar's contract ran out after Wrestlemania and would be returning to the UFC. "Even if I already know what's going to happen".
