Deontay Wilder knocked out Dominic Breazeale in one round, to retain his WBC heavyweight crown, at the Barclays Center in Brooklyn in the early hours of Sunday.
Wilder landed a huge right hand to stop Breazeale with his 20th first-round KO.
The American’s win keeps alive a potential undisputed unification showdown with three-belt champion Anthony Joshua.
“The power is real, it’s something that I don’t have to really train for.
“I think it will happen. It’s going to happen. I believe in all my heart it will happen,” Wilder told ringside reporters after the bout.
