Boxer left unconscious on his feet in final round of fight before devastating left-hook KO
Samuel Antwi pulled off a knockout of the year contender on Friday night against Mason Cartwright.
The pair clashed in Bolton in a battle for the British super-welterweight title and Antwi finished ended the fight in the twelfth round.
Antwi landed a crushing right hand on his opponent that left him unconscious on his feet.
But, at first the 31-year-old did not realise and so paused, almost confused as to why Cartwright was not fighting back.
He then followed up with a vicious left hook and right uppercut combination that saw Cartwright collapse to the canvas.
The referee immediately stepped in to wave off the fight, as Cartwright lay sprawled on the floor.

With that, Antwi, who is now 17-2 as a professional, takes home the British super-welterweight title.
He had attempted to win the same belt in the welterweight division last year, but lost to Ekow Essuman by unanimous decision.
But now, he finally has his hands on an iconic Lonsdale belt.
