Input: Amir Khan has been burning the midnight oil during Ramadan in case he finally gets the call to fight Floyd Mayweather in Las Vegas on September 12. Khan, a devout muslim, is currently observing the holy month by fasting from sunrise until sunset which has precluded him from any boxing training during the day. But the Bolton welterweight, still hopeful of landing the Mayweather fight in eight weeks, has found a way of staying sharp so he will be ready to face the pound-for-pound No 1 if he is chosen as his final opponent. Ramadan has been an incredibly busy period for Khan who has embarked on a 15-city tour of Britain in order to raise vital finds for the Amir Khan Foundation, which is building an orphanage in Gambia.Amir Khan still has hope that he will get to fight Floyd MayweatherMayweather says he will fight Andre Berto or Karim Mayfield in SeptemberKhan hits the gym at midnight to remain fit ahead of the potential bout
