Kell Brook's world middleweight title dream ended in a devastating fifth-round stoppage defeat by the fearsome Gennady Golovkin at London's O2 Arena.
Stepping up from welterweight to challenge one of the greatest middleweights in history, Kell did his reputation little harm but, as expected, was gradually out-boxed and over-powered by the defending champion.
The opening 90 seconds of the fight demonstrated the size of the task he was facing. Powerful hooks to both head and body clearly hurt Brook, threatening an early finish and forcing him to cling on.
Brook's right eye swelled and the fighter walked away from the ring with a broken eye socket.
Twitter couldn't believe Brook's courage last night.
