Mayweather confirms McGregor bout will be his last

Floyd Mayweather will be hanging 'em up after Aug. 26 - again.

In a Thursday conference call, the legendary boxer confirmed his upcoming blockbuster bout opposite UFC lightweight champion Conor McGregor will be his last. Mayweather first retired after outpointing Andre Berto in September 2015, but revealed he'd keep the promise he made to his inner circle and call it a career once again after he meets McGregor in Las Vegas.

"Actually, I thought Andre Berto, that was gonna be the last weigh-in. I thought that was gonna be the last training camp. I mean, honestly speaking, I thought that was gonna be my last everything, but you just don't ever know what can happen," Mayweather said.

"This is my last one, ladies and gentlemen. I gave my word to Al Haymon, I gave my word to my children, and one thing I don't want to do is break that. I gave Haymon my word, I gave my children my word, and I'm gonna stick to my word. This will be my last fight."

Over a career that has seen him go 49-0 and set a boxing record of 4.6 million pay-per-view buys for a 2015 superfight with Manny Pacquiao, Mayweather cemented himself as one of the greatest to ever grace the ring as well as one of the sport's preeminent defensive tacticians. "Money" boasts 15 world titles covering five weight classes, surpassing fellow luminaries like Mike Tyson and Evander Holyfield as boxing's greatest draw along the way.

His laundry list of conquests include the late Arturo Gatti, Oscar De La Hoya, Miguel Cotto, and Canelo Alvarez in addition to the decision he took over Pacquiao.

The 40-year-old Mayweather will look to cap his career with a perfect 50-0 record when he meets McGregor at Vegas' T-Mobile Arena in a 12-round, 154-pound tilt.
