Daniel Dubois will mount his latest IBF heavyweight title defence against Joseph Parker at Riyadh Season's The Last Crescendo,

The largest and most alarming scrap heap in boxing is in the heavyweight division, and both Parker and Dubois have flirted with the dirty pile over the last few years. The heap makes one-time contenders invisible, but Dubois and Parker have defied the odds, the science, and the sense to remain relevant.

Daniel Dubois has already beaten Anthony Joshua and next up for the revitalised heavyweight is Joseph Parker.

They don't step into the ring together until next month, but Daniel Dubois and Joseph Parker have already lobbed some bombs at each other.

Joseph Parker will be stripped of his WBO interim heavyweight title as soon as the first bell sounds for his showdown with Daniel Dubois next month
