LAS VEGAS -- Floyd Mayweather Jr. will come out of retirement to meet UFC star Conor McGregor in an Aug. 26 boxing match that will feature two of the top-selling fighters in the world.
The two fighters both announced the fight Wednesday, after months of speculation about whether Mayweather would be lured back to the ring at the age of 40 to face a mixed martial arts fighter who has never had a pro boxing fight.
Oddsmakers immediately made Mayweather an 11-1 favorite in a fight that will take place in a boxing ring and be governed by boxing rules. It will take place at 154 pounds.
"It's official," Mayweather said on Instagram next to a video poster of both fighters.
"THE FIGHT IS ON," McGregor tweeted several minutes earlier, posting a picture of himself next to one of Mayweather's father, Floyd Sr.
Mayweather, who retired in September 2015 after winning all 49 of his pro fights, will face the Irish UFC superstar at the T-Mobile Arena on the Las Vegas Strip. He had tweeted a picture of himself sparring in recent days to show he was already getting ready for the bout.
"This is really an unprecedented event," said Stephen Espinoza, who heads Showtime Sports, which will handle the pay-per-view. "Really we haven't seen anything in modern history that resembles it, it's impossible to predict how many sales this will do."
Espinoza said the fight came together quickly after McGregor and the UFC reached agreement last month on their end of the deal, and Mayweather's team pushed for the fight in recent days.
"All parties were motivated and reasonable and thrilled we could get everything done," he said. "The sky's the limit on this."
McGregor is 21-3 in MMA fights, and he is coming off a victory in November against Eddie Alvarez in which he became the promotion's first two-division champion. Although he hasn't boxed professionally, McGregor did box while growing up and is known for his striking expertise in UFC.
"The impossible deal is now happening," UFC President Dana White said on ESPN.
The two fighters are expected to do a media tour shortly before going into final training for the fight. The cost of tickets and the price of the pay-per-view have not been decided, although the pay-per-view is expected to be at or near the $99.95 charged for Mayweather's 2015 fight with Manny Pacquiao that drew a record 4.4 million pay-per-view buys.
Mayweather will come off a two-year retirement in a bout that McGregor has been pushing for nearly that long. It finally came together and Nevada boxing officials Wednesday approved the date for a Mayweather Promotions bout.
Mayweather last fought in September 2015, beating Andre Berto and then announcing his retirement. His fight before that, a decision victory over Pacquiao, was the richest in boxing history and reportedly made him more than $200 million.
Although oddsmakers made Mayweather a big favorite, the thought of the fight has excited many in the MMA world. It has also intrigued some in boxing, though most dismiss McGregor's chances under boxing rules against one of the greatest defensive fighters in history.
Oddsmaker Nick Bogdanovich, who set the 11-1 line at the William Hill chain of sports books, said the odds would be even more lopsided if it wasn't for the deluge of small bets expected to come in from UFC fans on their fighter.
"Realistically if we were just putting up a number and didn't have to take bets on it, Floyd would be 100-1," Bogdanovich said. "But this will be a very, very big betting fight for sure, one of the biggest ever."
Adding to McGregor's challenge, the fighters will be using 10-ounce boxing gloves instead of the smaller UFC gloves, and he will not be allowed to use the leg kicks or takedowns that are used in mixed martial arts.
Both fighters are noted for their ability to sell their fights, and both have exchanged in trash talking and more to promote their bouts.
"As with every Mayweather and McGregor fight, part of the appeal is the spectacle and outsize personalities who are participating in it," Espinoza said.
