Anthony Joshua stunned to win in 90 seconds

Cornish was expected to give Joshua a stern test, but the stoppage came in just a minute and a half at the O2 as the unbeaten Scot was sent to the canvas by the Olympic champion twice in quick succession.

Cornish did actually get to his feet in time, but the referee brought an end to the fight anyway.

"Credit to Gary where credit is due. He's a big man and had a solid jab," he said.

"It's a 12-round fight and I wasn't trying to dish it all out in round one, but I managed to find shots to get the job done.

"I was trying to slip his long solid jabs and counter him and he went tumbling down.

"If I leave it and start taking my time, then it could be me on the end of those shots in five rounds time.

"This is what you do it for. When I'm locked away, I lead a simple life in the gym, playing PlayStation and riding my motorbikes.

"Then I get to come out and give a display."

Joshua will fight Dillian Whyte for the British title at the O2 in December.
