He recently returned as the head trainer for his son, Floyd Jr who defends his WBC welterweight title against Robert Guerrero in Las Vegas on Saturday night, live and exclusive on BoxNation (Sky Ch. 437/Virgin Ch. 546).
Mayweather Jr had been trained by his uncle Roger who is expected to be in the corner at the MGM Grand Garden along with his brother and cutsman Rafael Garcia, but won’t be giving the orders.
Mayweather Jr said: “There are certain things my dad sees, and he only wants the best for me.”
The unbeaten American, 36, hasn’t boxed since a hard fought points win against Miguel Cotto 12 months ago, a performance that perhaps help persuade him to team up with his father.
Mayweather Jr added: “I don’t want to make the same mistakes I did for the Cotto fight, where I over-trained.
“I have had more rest than I did for the Cotto fight. It was all training and sparring which is wear and tear on the body.
“I shouldn’t have made the mistakes I did in that fight and against Guerrero I will be better than what I was in the Cotto fight.
My dad has said; ‘Look, you need the rest in training and you’ll look better.’ He was right.
“Any athlete competing at the highest level has to rest his body.”
