Boxing: Khan is sticking by his trainer.

Byline: By Phil Barnett

AMIR KHAN believes the first defeat of his career has given him a "kick up the backside" after being spectacularly knocked out in less than a minute by Colombian Breidis Prescott.

A stunning 54-second KO defeat in Manchester left his world title dreams in tatters with promoter Frank Warren admitting they would have to go "back to the drawing board." But Khan insisted he still has complete confidence in new trainer Jorge Rubio despite the Cuban suggesting Prescott as an opponent before watching his young charge get blown away by the bigpunching South American.

"Sometimes I let my heart rule my mind and it showed," said Khan. "I've been hit harder in my career but it was just at the wrong time, too early in the fight before I could get into it.

"I'm not going to let it get to me. Every fighter wins and loses in their career and I'm just going to come back stronger. Me and Jorge will work on my mistakes."

Khan thinks Rubio - who replaced Oliver Harrison after the Salford trainer was sacked earlier this year - is still the right man to guide his career in the ring.

"Yes, definitely," he said. "Training went really well but I happened to get caught with a shot by a power puncher.

"I'd definitely like to fight him again in the future. I know what mistakes I made and it's too late now. But I've never said no to anyone, I'll fight anyone.

"It's given me that kick up the backside in a way.

"I've got no excuses. The better man won. He caught me cold in the first round and I didn't recover from it."

Warren, who expects Khan to return to the ring when Nicky Cook makes the first defence of his WBO super-featherweight title on December 6, said: "We'll go back to the drawing board and think about the future.

"At the end of the day, whoever Amir fights the buck stops with me. When he's winning I'm a great matchmaker and promoter and when he loses I have to take the responsibility."
