UFC heavyweight and light heavyweight champion Daniel Cormier has his next fight booked.

Cormier will defend his heavyweight belt against Derrick Lewis next month at UFC 230. And the news didn’t sit too well with the fighter Cormier won the belt from earlier this year.

Stipe Miocic noted on Twitter that he believes he would beat Cormier “9 times out of 10. Everyone knows it.”

Obviously, Cormier feels differently about the matter and let Miocic know that he would be willing to face him after Lewis and if a potential match with Brock Lesnar fails to come available.
