Floyd Mayweather has called Maidana a 'dirty fighter' after claiming the Argentinian bit his finger during their rematch in Las Vegas.
Maidana denied the bite took place but replays suggest it was the reason Mayweather finished the fight – and completed his 47th straight victory – with only one good hand.
Mayweather won the fight over Maidana by unanimous decision with the judges' scorecards reading 115-112, 116-111 and 116-111 at the MCM Grand.
Maidana's protestations over the bite were weak at best, with the Argentine arguing: "He thinks I'm a dog, but I never bit him. I thought I won the fight but, if the judges want to give it to someone who runs, good luck to him. No, no, I didn't bite him. Maybe he put his glove in my mouth."
