Conor McGregor is serious. He wants Floyd Mayweather.
The most popular fighter in the UFC has received a boxing license in California.
The #ConorMcGregor and #FloydMayweather camps have reportedly been in talks for nearly a year, according to Flocombat.com, and that the acquisition of the license is "the next step" toward a possible monster inter-sport fight.
McGregor KO'd Eddie Alvarez at UFC 205. During the fight he displayed a superior level of boxing, picking apart Alvarez with wicked left hands. With the victory, McGregor became the UFC's first champion to hold world championships in two divisions simultaneous, and solidified his spot as the biggest draw in the company. He has also emerged as a crossover star with his "#billionairestrut" being copied by several athletes in other sports.
McGregor has been angling for a fight against Mayweather. The 39-year-old retired in 2015 with a record of 49-0 and is widely regarded as one of the best boxers of all time.
The acquisition of the license indicates that McGregor isn't just talking about the fight. It appears that he may be interested in making the jump to boxing, at least on paper.
The Mayweather camp, however, doesn't appear impressed.
Leonard Ellerbe, CEO of Mayweather Promotions, told ESPN.com that people shouldn't hold their breath for a mega fight.
"It's all a game," Ellerbe said. "It's all a calculated effort to gain more fans. He got a boxing license. Congratulations to him. Conor McGregor can say anything he wants to but he has a boss and his name is [UFC president] Dana White. He is under contract to the UFC and if he wanted to fight Floyd Mayweather in a boxing match he can't because his bosses wouldn't allow that to happen. "
Mayweather made his pro boxing debut 20 years ago and has defeated the best boxers in the world. He holds victories over Manny Pacquiao, Oscar De La Hoya, Juan Manuel Marquez, Shane Mosley and Canelo Alvarez, just to name a few. He is considered one of the sport's best defensive fighters.
Ellerbe said McGregor would get beat "from pillar to post."
"The brass [from WME-IMG] who recently purchased the UFC [for $4 billion earlier this year] are very smart people and they would never -- and put this in bold caps -- let him step into a boxing ring with Floyd Mayweather because everyone knows what the outcome would be. He would get his ass beat from pillar to post," Ellerbe said.
Ellerbe noted that McGregor tapped out in a fight earlier this year.
"Go out there and worry about dominating the UFC because three fights ago he lost, he was quitting," Ellerbe said. "You couldn't even mention the word quit with Floyd Mayweather. And, like I said, [McGregor] can't do anything without the UFC's approval. There's no way [WME-IMG] spent all that money so they can get their biggest star killed. It would never happen. If they want to get him killed put him in there in a boxing match."
McGregor earlier this week also posted a $100 million check that he earned from his 2015 Manny Pacquiao fight and said he was "happily retired."
While the UFC and boxing are both combat sports, they are entirely different disciplines and many observers question whether a sanctioning body would ever allow a fight between a skilled legend like Mayweather, against a guy who would essentially be making his professional boxing debut against one of the greatest fighters ever.
