Amir Khan has hit back angrily at allegations that he has used steroids to boost his climb through boxing?s weight divisions.
The uncle of Floyd Mayweather Jnr, who Khan hopes to meet in a mega-fight next year, has linked Britain?s world light-welterweight champion to the family?s claims that Manny Pacquiao?s ascent to become the best pound-for-pound boxer on the planet has been achieved by drug abuse.
Roger Mayweather voiced suspicions because Khan is in the same stable as Pacquiao under master trainer Freddie Roach.
Khan, 24, said: ?I?ve consistently proved that I am a clean fighter. This is nonsense. I?ve been tested repeatedly in my career, before and after fights, at home and my base in Los Angeles.
?Don?t forget that I came through the Olympics (in 2004) where testing is very thorough. I?ve never refused the test, even though I could have done so when I received an unannounced knock on the door a month after my last fight against Paul McCloskey.?
