Mayweather himself revealed on social media that the fight will finally happen on August 26 at the T-Mobile Arena in Las Vegas.
McGregor, for his part, also confirmed the slugfest.
Meanwhile, UFC President Dana White laid out the details of the match:
-It will be a boxing match, in a boxing ring
-There will be 12 rounds
-The catch weight is at 154 pounds
-The fighters will use 10-ounce boxing gloves
-Mayweather Promotions will handle the undercard
Major news indeed for fans of both combat disciplines as this can easily go down as this year's biggest sporting affair. Here are some previous and new reactions from known fighters and other personalities in the MMA and boxing sphere:
The boxing press don't seem too fond of the fight
Same goes for the boxers who think Floyd will school McGregor big-time
But we have mixed reactions from the MMA side
Prior to this confirmation, everyone including the media and industry experts thought that the bout was never going to happen, especially since it had never been done before. Mayweather is also known to drag his feet when it comes to giving fans the fight they want.
But now, we're suddenly two months away from the dream megabout that at first seemed impossible to pull off. Let's take a look back at how all this started.
July 2015 - The whole issue began when, way back in July 2015, Conor said during the Conan talk show that he was open to boxing Mayweather and will 'dismantle' the undefeated boxer in his own turf.
Floyd didn't directly respond to Conor's comments but his dad, Floyd Mayweather, Sr. did and he scoffed at the idea.
December 2015 -Floyd talks about racism in sports and mentions how Conor talks a lot of trash and gets admired for it, while he's branded as the bad guy when he does it.
January 2016 - Conor calls Floyd out for his 'racist' comments:
Floyd's response: 'If he got offended, that's life'
May 2016 - Floyd starts saying that he believes a fight between him and Conor McGregor will happen:
However, Conor made it clear that he wants nothing less than $100 million, a figure that Floyd seems unwilling to split with the UFC champion.
September 2016 - Floyd says negotiations for the Mayweather-McGregor fight have fallen apart:
November 2016 - After the failed negotiations, Mayweather says to 'Never compare Conor McGregor to me. That's a total disrespect.'
Despite what happened, Conor acquires a boxing license in California and disses Floyd.
December 2016 - Floyd posts a potshot video on Instagram, where he called Conor a 'bitch' for his earlier loss that same year, tapping out against Nate Diaz in UFC 202. The video has been remixed and has since gone viral.
January 2017 - Floyd tells ESPN that he is willing to give Conor a guaranteed $15 million to fight him.
Dana White chimes in and says he will give Floyd and Conor $25 million each plus a split in pay-per-view revenue.
March 2017 - Here's when the crucial part starts. Floyd publicly states that he was coming out of retirement to fight Conor. He then challenges Conor to sign the contract to get the fight done and over with in June.
May 2017 - Dana White says they blew the date on the potential megabout and it was the UFC side's fault:
In a surprising turn of events, and Conor finally signs the contract and dares Floyd to do the same.
June 2017 - Floyd, Conor, and Dana finally confirm that the fight is happening on August 26.
So between Floyd and Conor, who you got?
