We got a heavyweight slugfest on our hands.

Stipe Miocic will try to defend the UFC heavyweight title belt against rising star Francis Ngannou at UFC 220.

Ngnannou has a way of coming off as a monster when he competes in the Octagon, but outside of the cage, he comes off completely different as he is quiet, soft-spoken, humble man.

That wasn’t the case at last week’s UFC 220 press conference in Las Vegas.

Miocic took the first couple questions from the media with one asking if the UFC heavyweight champion felt a hint of intimidation after seeing Ngannou’s sick knock out Alistair Overeem. When Miocic began answering that he felt none, Ngannou interrupted.

“Don’t lie, Stipe. Don’t lie,” Ngannou said.

More of Ngannou’s new personality was on display on Twitter in response to a tweet by Miocic:

“Andrei Arlovski — RD1 0:54

Fabricio Werdum — RD1 2:47

Alistair Overeem — RD1 4:27

Junior dos Santos — RD1 2:22

Francis Ngannou — 1/20 #AndStill”

Ngannou fired back by stating, “Lol . Just 16 days to go . January20th #UFC220 #AndNe....w !!!”

UFC 220 is set to take place on Saturday, January 20, 2018, at TD Garden in Boston, Massachusetts. The main card will air on pay-per-view while the preliminary card will air on FOX Sports 1 and the promotion’s streaming service, UFC Fight Pass.
