Ukrainian champion Oleksandr Usyk knocked out Britain’s Daniel Dubois in the ninth round to retain his WBA, WBO and IBF heavyweight world titles.
Usyk, fighting in front of a partisan 40,000-strong crowd in Poland, knocked Dubois down at the end of round eight.
And in the next round, a tiring Dubois was sent to the canvas again and failed to beat the count.
Usyk took several minutes to recover in round five after being hit with a punch that the referee deemed to be low.
