Amir Khan showed off his boxing skills with one of his best performances when beating America's Dmitriy Salita.
Khan needed only 76 seconds to win the bout, against a opponent who had never been beaten in 31 fights.
Khan knocked Salita down three times in the first round, and then the referee decided it wasn't safe for him to carry on, so stopped the bout.
The victory means Khan is still the WBA light-welterweight world champion, with 22 wins and one loss from 23 fights.
Before the bout Khan had been talking about fighting in America next, but afterwards seemed to have rethought his plans.
Amir Khan is still world champion
He said: "After that reception tonight, I would love to fight in England again.
"Next year some time I want to go to the States. Hopefully we will shock the world when I go to America. It's my dream to fight in Las Vegas.
"I'm still 22 and I have a long way to go yet. I'm just growing into a man and I haven't hit my peak yet. I can only get better."
