Retired American boxer Floyd Mayweather threw down the gauntlet after UFC's Conor McGregor announced his retirement from the fight game.
The 31-year-old McGregor posted on Twitter on Saturday (Sunday in Manila) that he has "decided to retire from fighting" -- the third time since 2016 that he used the social media platform to claim that he was stepping away from mixed martial arts.
The next day, McGregor posted a photo of a cake on Instagram, with the icing reading "Happy retirement, Daddy."
Mayweather was one of the thousands to comment, saying: "If I'm not mistaken, didn't you tell Mike Tyson that you could beat me if we fought a second time? Now you're quitting!"
"I thought you wanted to beat the best? Well, if you decide to come back, I will be waiting to punish you again."
Mayweather and McGregor fought in August 2017, with the American winning via a 10th round technical knockout. The win hiked Mayweather's record to a perfect 50-0, and he retired afterward. Mayweather did fight Japanese kickboxer Tenshin Nasukawa in an exhibition match in December 2018.
McGregor told ESPN in an interview that he is "a bit bored of the game."
"I'm just not excited about the game. I don't know if it's no crowd. I don't know what it is. There's just no buzz for me," he explained. "All this waiting around. There's nothing happening. I'm going through opponent options, and there's nothing really there at the minute."
"There's nothing that's exciting me."
McGregor last fought in January 2020, when he knocked out Donald Cerrone in just 41 seconds, in what was his comeback after a 15-month layoff. He has a record of 22-4, and was the first UFC fighter to hold two championships at the same time. -- With a report from Agence France-Presse
