Floyd Mayweather should walk away from boxing after his showdown with Manny Pacquiao, his father has advised.
The welterweight kings collide in Las Vegas on 2 May, with Pacquiao looking to deliver the first defeat of the five-weight world champion's glittering career.
It is the penultimate fight of Mayweather's contract with broadcaster Showtime and the 38-year-old has previously indicated he will retire from the ring after the last bout of the deal, which is likely to be held in September. But Floyd Mayweather Sr believes his son should call it quits at the top after the Pacquiao fight.
In an interview with the Sunday Telegraph, Mayweather Snr said: "I hope that Floyd gets out the game at the right time. This is a gambler's game and I don't think Floyd should be gambling too much.
"Once you reach that pedigree and make that kind of money, you don't have to fight no more. I hope he walks away after this fight. Whenever you get in that ring, anything can happen. It looks easy but it ain't as easy as it looks. He makes it look easy."
While he is hoping his son leaves the ring for the final time after the MGM Grand showdown, Mayweather Snr has no doubt he will do so still unbeaten and having added Pacquiao's WBO title to his collection.
"This era is closed. It's done. Pacquiao is done," he said. "He needs to be locked up in jail because it's time to save his a**. Pacquiao needs to lock himself up. He is not on Floyd's level. All he is, is an opponent. That's all he is. Nothing more, nothing less."
