LAS VEGAS (Reuters) - Floyd Mayweather Jr rarely hands anyone a rematch and Argentine brawler Marcos Maidana is hoping to make the undefeated welterweight champion regret giving him a second chance when the fighters meet again on Saturday.
For only the second time in his brilliant 18-year career, Mayweather will face an opponent he has met before when he puts his 46-0 record, World Boxing Association (WBA) and World Boxing Council (WBC) title belts on the line in Las Vegas.
