Gennady Golovkin beat Britain's Kell Brook with a fifth‑round stoppage to retain his WBC and IBF middleweight boxing titles in London.
The 34‑year‑old from Kazakhstan won a gripping, gruelling battle as Brook struggled to see out of his right eye.
Welterweight world champion Brook jumped two weight divisions to challenge for Golovkin's belts.
And he put in a sterling challenge before his trainer Dominic Ingle asked the referee to halt the fight.
