Amir Khan made a stunning debut to his professional career by stopping opponent David Bailey after just 109 seconds of their fight in Bolton. Khan floored his opponent almost as soon as the bell went and knocked him down again very quickly.
The towel appeared to come in from Bailey's corner but the referee seemed not to notice and the fight continued.
Bailey threw a couple of punches but was caught by another fierce delivery from Khan and the referee stepped in.
Khan entered the ring to "Land of Hope and Glory" and dedicated his victory to the victims of the London bombings.
Afterwards, he admitted he had been a bit nervous about his professional debut.
"I was a bit nervous because it was my first fight - I'm going to go home and watch the video and see how it was," said the teenager.
"I want to be one of the youngest British world champions ever and hopefully it will happen."
