Dubois stops Hrgovic as Zhang knocks out Wilder

Britain's Daniel Dubois took a huge step towards heavyweight world title contention after stopping IBF mandatory challenger Filip Hrgovic in the eighth round of their fight in Riyadh on Sunday.

Referee John Latham intervened 57 seconds into the round on doctors' advice at the Kingdom Arena with the big Croatian bleeding from cuts over the eyes.

The fight was for the interim belt, which could become a world championship title if Ukraine's undisputed world champion Oleksandr Usyk relinquishes his or is stripped by the sanctioning body.

Deontay Wilder meanwhile saw his hopes of a potential showdown with Anthony Joshua fade away as he suffered a fifth-round knockout defeat to Zhilei Zhang in the night's main event.That fight could instead now fall to Dubois, who seemingly put himself in pole position for a title fight against the former unified champion.

"I've heard the next opponent will be AJ, so bring it on," Dubois told DAZN after the outstanding performance of his career to date. "I'm anxious to become the best, this is my era and my time.

"I'm glad I've got this IBF belt and on to the next."
