Members of the Mayweather boxing family continued to criticize referee Tony Weeks, this time with Jeff Mayweather saying the official "dropped the ball" during the Floyd Mayweather-Marcos Maidana bout last May.
The American superstar won the fight via majority decision, but later criticized Weeks for allegedly allowing Maidana to get away with "dirty tactics" all throughout the 12-round fight.
Meanwhile, his father and trainer, Floyd Sr., has called for a different referee for the rematch between his son and the Argentine brawler in September.
Jeff, another of Floyd's uncles, recently added to the criticism in an interview with Hustle Boss.
"I really respect Tony Weeks as a referee," said Jeff, "but he dropped the ball that night, and he did a horrible, horrible job."
Jeff added, however, that expects the rematch to be a cleaner affair.
"It's boxing, so if you can get away with something, get away with it. He (Maidana) was a very dirty fighter, and whoever is refereeing (the rematch) is not gonna let that happen this time," he said.
"I think that it will be a much cleaner fight," he added.
Having observed his nephew in training, Jeff also believes that Mayweather will "win a little easier" this time around, after finding himself in trouble against Maidana's relentless pressure in the first fight.
"(Floyd will) probably box a little bit more" in the rematch, Jeff said, noting that his nephew will definitely make adjustments after seeing what Maidana was capable of.
"Floyd has the highest IQ in boxing, so you know, he can change at any moment in the fight. And that's the advantage he has over everyone – being able to make those adjustments," he said.
