Trainer Jeff Mayweather, the uncle of retired pound-for-pound king Floyd Mayweather Jr. (49-0, 26KOs), does not expect his nephew to return in 2016.

Floyd retired in September after winning a twelve round unanimous decision over Andre Berto at the MGM Grand in Las Vegas.

Mayweather has retired at least twice in the past and came back to the sport. Many insiders believe he will return once again next year to break Rocky Marciano's record of 50-0.  

The WBC has already stripped him of his welterweight and junior middleweight titles. The WBA is expected to follow the same path during their annual convention this week in Panama.

"I think that he’ll stay retired. There’s nothing left to prove. The only thing that people want is for him to break Rocky Marciano’s record, and at the end of the day that record doesn’t really mean that much. At the end of the day, 49-0 or 50-0 is not gonna mean anything when you’re talking about a guy who’s been undefeated for nineteen years. It’s never been done in no sport, that’s the record that means something," Jeff told On The Ropes Boxing Radio.

"Fighting more world champions than anyone else, making $800 million in the ring, those are the things that will probably never be surpassed and those are the records that are really the records. It’s his choice, it’s up to him. Floyd’s legacy is intact, you can hate him, you can love him, it doesn’t matter because one thing that doesn’t lie is the numbers, the numbers don’t lie. When Floyd says that he’s the best ever, that’s exactly what his numbers said, because he outdid everybody in every sense of the word of boxing."
