Bob Arum believes Floyd Mayweather's declaration that he will soon retire after sensing the unbeaten American has fallen out of love with boxing.
Arum's Top Rank are joint promoters of Mayweather's showdown with Manny Pacquiao in Las Vegas on Sunday in what will be the penultimate assignment of the 38-year-old's six-fight deal with Showtime.
Toppling Pacquiao at the MGM Grand would register a 48th victory and leave him just one short of equalling Rocky Marciano's hallowed 49-fight unbeaten mark.
Mayweather's insistence that he has no desire to eclipse Marciano has been met with widespread scepticism but Arum, who promoted the reigning pound-for-pound king for the first decade of his career, predicts he will soon hang up his gloves.
I believe what Floyd is saying in that he is looking towards retirement. He's been at it since he's eight years old and he doesn't enjoy it like he used to.
Like Marvin Hagler said, millionaires sleep in silk pyjamas and don't like to get up in the morning and do roadwork.
When he retires, I think Floyd will be a great party guy. He'll have plenty of money and he'll enjoy himself. I just hope that for his sake he settles down and lives a more normal family-type life.
Freddie Roach believes Floyd Mayweather has been forced into a fight he would rather avoid and questions whether the American will even turn up for his welterweight epic against Manny Pacquiao.
Mayweather and Pacquiao collide in Las Vegas in the early hours of Sunday morning with the outcome of the showdown at the MGM Grand deciding who is the greatest boxer of their generation.
Roach believes the 38-year-old's television paymasters Showtime, who have outlaid a minimum of £130million for a six-fight contract, ordered the clash the boxing world has craved for the last five years.
I don't know why Floyd's been so quiet. I'm wondering if he's going to show up, I really am.
At the first press conference I said we were going to kick his ass, but there was no response. His speech was very low-key and subdued. I'm not sure he is going to show up.
I think Floyd was forced into this fight and it's not a fight he wants. He always gets to pick and choose his opponents, but he wasn't able to pick and choose this one because Showtime wanted this fight.

Boxing fans hoping to attend the weigh-in for the welterweight showdown between Floyd Mayweather and Manny Pacquiao on May 2 must buy advance tickets.
The vast numbers expected to attend the eve-of-fight ritual at the MGM Grand Garden Arena has prompted fight organisers to take the step of charging for entry to the event.
Tickets will cost £6.60 and will go on sale through MGM Resorts call centre and box office on Friday at 8pm with all funds raised going to the charities chosen by Mayweather and Pacquiao - Susan G. Komen and the Cleveland Clinic Lou Ruvo Center for Brain Health.
"The weigh-in is always the grand finale of fight week activities," said Mayweather Promotions chief executive Leonard Ellerbe.
"And with the massive interest in this fight, the number of fans looking to attend the official weigh-in is going to be something we've never seen before.
"We're excited to be able to use the enthusiasm around this event to provide donations to two very deserving charities."
A mere 500 tickets were made available to the public for the clash between the two best fighters of their generation.
These sold out in minutes with resale prices on secondary seller StubHub ranging from £3,900 to £85,000 on Friday morning.

Kenny Bayless has been appointed referee for the superfight between Floyd Mayweather and Manny Pacquiao in Las Vegas on May 2.
Bayless, a veteran of more than 100 title contests, has overseen five of Mayweather's bouts and has been present seven times with Pacquiao.
The 64-year-old Nevada resident was referee for their points victories over Shane Mosley, one of the rivals' five common foes.
The Nevada State Athletic Commission have also appointed a trio of American judges for the clash at the MGM Grand in Dave Moretti and Burt Clements of Nevada and Glenn Feldman of Connecticut.
"Kenny knows the pressure, stress and responsibility," NSAM director Robert Bennett said.
Former two-weight world champion Ricky Hatton believes British compatriot Amir Khan could be the man to dethrone Floyd Mayweather as boxing's pound-for-pound king.
Khan has been seeking a showdown with Mayweather for nearly two years, but the American WBC and WBA welterweight champion has spurned the Bolton fighter's advances at every turn.
That does not come as a surprise to Hatton, who believes Khan's blurring punches and rapid movement could be the key to handing Mayweather his first professional defeat.
I think Floyd would run a mile from Amir Khan, not because of a fear factor, but because styles make fights," Hatton said in several national newspapers.
Amir is boxing with a lot more discipline lately, he's in and out and he's not getting involved. I think that type of style will cause Floyd massive problems.
But, when you're the best, pound-for-pound, like Floyd Mayweather - and Amir's as big a name as is out there, he's beaten pretty much everyone - he might be forced to fight Amir Khan.
He might be running out of opponents. I say this all the time, and everybody laughs at me: I think he's got a good chance of beating him.
