• Zhang knocks out Wilder, Dubois stops Hrgovi - as it happened

Deontay Wilder's career as an elite heavyweight came to a crashing end. For Daniel Dubois, the journey into the top flight is only just beginning. And the unceasing, unsentimental round-and-round of boxing's glamour division turned in dramatic fashion early Sunday morning in the an-Nafud desert.

Wilder, who held the WBC's version of the heavyweight title from 2015 through 2020, suffered a brutal fifth-round knockout at the hands of Zhilei Zhang in the main event of a joint Matchroom-Queenbury card that pitted the stables of British boxing's leading promoters against one another.
