Frank Warren has confirmed "it's Joseph Parker's time" when discussing Oleksandr Usyk's next opponent.
Usyk beat Daniel Dubois for a second time on Saturday night at Wembley, producing a brutal fifth-round knockout to retain his WBA, WBC and WBO belts and regain the IBF belt he relinquished just over a year ago.
A brutal left midway through the fifth round brought an end to the bout, which the unbeaten Ukrainian dominated from the first bell.
Asked after the fight who he will face next, Usyk simply replied: "I don't know. I want to rest. I want to go back home to my wife, my family."
Pushed for an answer, Usyk listed off four contenders. He added: "Maybe Tyson Fury?
"Three options, Derek Chisora and Anthony Joshua. Maybe Joseph Parker. Listen, I cannot say because I want to go back home."
Warren, Dubois' promoter, then confirmed that Parker is the mandatory challenger.
"The WBO have already ordered that he has to make his mandatory defence against Joseph Parker, it's Joseph Parker's time."
