Relive the moment Ukrainian 28-0 ace Viktor Postol announced himself on boxing’s biggest stage as he outgunned Argentine slugger Lucas Matthysse in October 2015.

The Ukrainian dropped to his knees in sheer delight after he iced Matthysse, owner one of boxing’s biggest punches, to win the WBC World Super-Lightweight Title.

"That is a knockdown, we’ve got a count! Matthysse is down. And this is over! Viktor Postol has knocked out Lucas Matthysse!"

Then 27-0, Postol was relatively unheralded for a man with his stellar record. He'd notched undercard wins over Selcuk Aydin and 17-2 Jake Guiriceo in the States, but nothing close to the magnitude of his stunning KO win over Matthysse, who had never before been stopped.

WBC King Postol is a clinical tactician in the ring; he's nicknamed "The Iceman" for a reason. He stands tall for 140lbs at 5ft 11in with 73½in reach, giving him significant physical advantages over Saturday night’s unbeaten opponent, 28-0 WBO Champ Terence Crawford.

What’s certain is that we’re in for an absorbing contest between the division’s current top two fighters. Freddie Roach-trained Postol, 32, has guaranteed he’ll end the undefeated reign that has seen Nebraska’s Crawford tipped as a pound for pound contender.
