Floyd Mayweather Sr says his son will have to think long and hard about making a comeback, though the decision lies entirely with him.
Mayweather Jr officially bowed out of the sport after his points victory over Andre Berto earlier this month.
That win took his record to 49-0, tying the all-time undefeated record of Rocky Marciano.
Mayweather needs just one more win to make the record his own, and while many expect him to come out of retirement at some point to do just that, his father is urging him to consider whether he still has the motivation required.
"All of them top guys, he beat all of them. What is he supposed to do, go back and beat them again?" the 62-year-old told Boxingscene.
"Boxing don't go like that. When you get to a certain stat, my son already broke all the stats. There ain't nothing left for him to do but fight when he wants to fight.
"I can't choose that for him. I can only say what I want to say. I can't speak for him. He's a grown man. I know what I would do. I would walk away because ain't nothing prove. All everyone in boxing wants today is a bunch of money and he's got that so what else?
"It ain't like he's got a little money. He's got a whole bunch of money. There ain't no reason to show nothing if you ain't feeling like it. I don't care what people say. If you ain't feeling it, don't do it."
