Mayweather's father pushing for Khan fight

Floyd Mayweather Jr has vowed to put Amir Khan "on his backside" if they ever fight - to keep his dad happy. Khan and Mayweather Jr traded verbal blows throughout the summer after the American chose to fight Marcos Maidana even though the Bolton fighter proved a clear winner in an online fans poll set up by 'Money' himself. But Mayweather Jr said a fight with Khan could be now on the horizon beacause his father wants it to happen. "My Dad is desperate for me to take [the Khan fight] he just wants me to shut the kid up and put him down," Mayweather told the Daily Mail.
