Manager David Higgins has speculated on the timing of Joseph Parker's chance to fight unified heavyweight champion Oleksandr Usyk. 

The World Boxing Organisation has ordered Usyk to take a mandatory defence of his WBO title against Parker, which would also likely put his remaining alphabet soup of belts on the line. 

The news came hours after reports of Usyk's camp negotiating for an undisputed bout with IBF champion Daniel Dubois, who allegedly pulled out of last month's fight with Parker due to illness. 

Higgins told Mike Hosking that at the end of the day, who Usyk fights will be up to him. 

But he says if he chooses to ignore the order by the WBO, he’ll be stripped of his title.
