Chicago - WBA/WBC welterweight champion Floyd Mayweather Jr. and trainer Robert Garcia continued to unload verbal bombs on each other at the Chicago press conference to promoter the undefeated fighter's September 13th rematch with Marcos Maidana at the MGM Grand in Las Vegas. Garcia went after Mayweather for his verbal jabs regarding Diego Corrales, betting money with Maidana, and the issue of the gloves - and then Mayweather continued to downgrade Garcia's record during his professional run as a fighter.
