Amir Khan is staying mentally and physically ready, stating that he won't allow WBC/WBA welterweight champion Floyd Mayweather Jr. to gain an advantage by catching him off-guard with a last minute announcement.

The boxing world is still waiting for 'Money' (48-0-26KOs) to confirm his opponent for September 12, but despite reports suggesting it will be Andre Berto, Khan is not giving up on trying to taunt Mayweather Jr. into springing a surprise.

He feels there may be a chance that Mayweather is using Berto's name to play a mind game. Berto and Khan are training partners under coach Virgil Hunter.

Khan told Sky Sports:  "I know how Floyd works. The Pacquiao fight was only announced six weeks before it happened so I think there's a good chance the fight between me and him can happen as well. It's all about me staying in shape.

"I don't want Floyd to catch me off-guard so I need to keep in the gym and keep busy until he announces who he's going to fight. I think the whole world of boxing is waiting for Floyd's decision before they can make their own moves."

Mayweather was last in action in May when outpointing Pacquiao while Khan (31-3-19KOs) scored a unanimous decision over Chris Algieri during the same month.
