McGregor, 28, has never boxed as an amateur or professional and has roundly been written off by experts who say he has no chance against Mayweather, but Kavanagh feels his man is already shaping up well.
The PPV will cost $89.95 to purchase in standard definition.
Tickets for the fight will be available through the T-Moblie Arena website. The venue holds 18,000 fans, though a limited number of seats will be sold.
The cheapest seats in the house will cost $500, according to MMAFighting.com, while ringside seats are set at a staggering $10,000. Ticket prices then jump up to $1,500, $2,500 and $3,500.
Bless the hearts of two fighters who can walk away from an unforgiving game young and rich, or at least relatively so in Mayweather's case.
"If you believe in yourself, like you say you believe in yourself, bet your whole fight check", Mayweather added.
Nevertheless, Mayweather can walk up close and torch McGregor in Los Angeles while White looks on laughing, just as "Notorious" can stroll up and pummel the pound-for-pound great over his inability to grasp literacy with Ellerbe damn near hysterical in the background. I don't know what that got to do with race. "I'm not sure how much is a put on. I'm going to knock him out inside four rounds mark my words", as per Indian Express report.
Yes, he had one more f-word in him.
"If I come out good out of this next fight, I'm looking at October-November", she said. Depending upon the PPV buys, his final payday could reach $100 million.
In 2016, prior to a fight against Nick Diaz, McGregor called him a "cholo gangster from the hood". He last boxed in September 2015, defeating Andre Berto in a unanimous decision retaining his title.
Perhaps the American was contenting himself with the knowledge that if McGregor had arguably won round one of their verbal jousting the 12-time world champion has been installed as the heavy favorite for their August bout.
During the first press conference, Mayweather was making a speech when he stopped and showed off some shadow-boxing moves in front of McGregor. He'll turn 41 years old in February.
