Mayweather confirmed he is ready to rumble via social media on Wednesday.
"Nobody is bummed out about this deal", UFC president Dana White said.
Ellerbe was asked when McGregor started to get Mayweather's attention.
McGregor, the wildly popular UFC star, is 21-3 in UFC fights, and is coming off a win in November against Eddie Alvarez. Now it's time to work on the other. "I don't think boxing is the style of fighting that can beat Floyd but there are many many forms of fighting that can beat him so if were to get it on I would most certainly dismantle him also".
While the official figures are not out as yet, several reports are claiming that the fight night has the potential to become the most lucrative ever in the history of combat sports, with fans possibly needing to spend their entire lifetime savings to catch a glimpse, LIVE from the stands. "Guys who have the love for the sport and love what they do - and love the attention, and giving the fans what they want to see - that's what they do". The mega-fight between Mayweather and Manny Pacquiao generated a record 4.6 million PPV buys in 2015, leaving Mayweather with a final check worth between $220 million and $230 million, according to ESPN. He's got to get his ass up and be prepared for Conor McGregor.
'When Conor connects, people fall and they don't wake up.
Mayweather is the strong favourite but Holm, who will face Brazil's Bethe Correia in Singapore, said fights can be unpredictable.
While terms are still unknown, it's been reported that Mayweather would get the larger purse, potentially as high as $100 million, according to White, likely the motivation in luring him out of retirement and risking his flawless 49-0 career record.
Mayweather's pay-per-view record eclipsed the previous best for his title fight against Oscar de la Hoya in 2007, which pulled in 2.48m. "Really we haven't seen anything in modern history that resembles it, it's impossible to predict how many sales this will do". The 12-round fight will be fought at 154 pounds and will mark a return to the ring for Mayweather after an nearly two-year layoff. Pacquiao reportedly earned $100 million for his efforts. "So, I [applaud] Conor for getting this fight", she said.
