Deontay Wilder suffered his second consecutive loss in Riyadh after he was stopped by Zhilei Zhang in the fifth round.
"Big Bang" landed a huge right hand as Wilder looked to land one of his own, spinning "The Bronze Bomber" around before Zhang followed up with another shot that sent him to the canvas.
The main event win for Zhang made it a clean sweep for Frank Warren and Team Queensbury in their 5 v 5 clash with Matchroom and Eddie Hearn.
It also means that Wilder has lost four of his last five, beating Robert Helenius in between his losses to Zhang and Joseph Parker and back-to-back defeats at the hands of Tyson Fury.
Many have suggested that this could be the end for Wilder, who was undefeated at 42-0-1 until the rematch with Fury.
