Moses Itauma leaves Demsey McKean folded on the canvas with brutal first-round KO on Fury vs Usyk undercard

MOSES ITAUMA knocked 6ft 6in former kickboxer Demsey McKean out in a single savage round.

The 19-year-old Chatham wonderkid was supposed to get a serious test against the giant Aussie on the undercard of Tyson Fury's rematch with Oleksandr Usyk.

But the sensational southpaw dropped the 34-year-old with a magnificent right-hook-left-hand combination in the opener.

And when ref Bob Williams let the action carry on after an eight count - perhaps unwisely - Itauma used the same combination to send McKean back Down Under.

The towering tattooed test took Filip Hrgovic 12 rounds in August and he kept warning Itauma in the Riyadh build-up that he had taken on more than he could handle.

But the freakishly talented teen rammed those words - and both his fists - down his throat to continue his ridiculously fast rise toward a world title.

Itauma started off stabbing to the stomach with his jab and he soon realised that made McKean drop his guard.

The next time feinted a body dig he switched the target of the attack and battered McKean’s brain.

The tough veteran deserves credit for getting up but it was a very brief resurrection and he was buried again swiftly after.

Itauma celebrated his latest faultless step-up by racing to the ropes and making a cut-throat gesture to the growing crowd.
