Champion boxer Floyd Mayweather has claimed his 47th straight fight by beating Argentine slugger Marcos Maidana in a bad-tempered rematch that was marred by bite claims.
Mayweather, who hasn't lost a fight since the 1996 Olympics, successfully defended his World Boxing Association and World Boxing Council welterweight belts and the WBC junior middleweight belt in a unanimous points decision.
But the bout was engulfed in controversy as Mayweather accused Maidana of biting him.
