Former world champion Floyd Mayweather has announced he will come out of retirement for a fourth time later this year.

The 48-year-old, whose most recent retirement was in 2017, is due to face former undisputed world heavyweight champions Mike Tyson in an exhibition bout this spring. 

But Mayweather has confirmed he will return to professional boxing for the first time in nine years after that fight. 

While an opponent has not yet been announced, it will be Mayweather's first professional fight since beating mixed martial arts fight Conor McGregor with a 10th-round technical knockout in 2017. 

Mayweather won titles across five weight classes during his career, and his victory over McGregor secured his 50th professional win to remain undefeated.

"I still have what it takes to set more records in the sport of boxing," Mayweather said in a statement.

No details of date or location for the fight have been released.

He continued: "From my upcoming Mike Tyson event to my next professional fight afterwards - no one will generate a bigger gate, have a larger global broadcast audience and generate more money with each event - than my events." 

Mayweather previously retired in 2007 (twice) and 2015, and since he left the sport again as a professional after his 2017 victory over McGregor, he has competed in a number of exhibition bouts, with his last outing coming against John Gotti III in August 2024. 

During his career, Mayweather has headlined the three highest-grossing bouts in history against eight-weight world champion Manny Pacquiao, Mexican pound-for-pound great Saul 'Canelo' Alvarez, and McGregor.
