The 42-12 months-aged built the announcement on his Instagram account, and also reported he is functioning with UFC boss Dana White to “bring the environment another stunning event.”
Mayweather, who was undefeated in his career with a report of 50-, is thought of one of boxing’s all-time greats.
He came out of retirement in 2017 for his final skilled boxing struggle versus UFC star Conor McGregor.
Following beating McGregor, a UFC rematch in the octagon was proposed, despite the fact that nothing concrete ever materialized.
In a bout that past just 140 seconds, Mayweather attained a reported $9 million (£7m) for beating the Japanese fighter.
In October, Philippines boxing legend Manny Pacquiao and Alibaba founder Jack Ma challenged Mayweather to a struggle.
“Floyd Mayweather, if you want a real struggle, struggle me. If you want an exhibition, my person, my close friend, Jack Ma will consider treatment of you,” Pacquiao mentioned.
Mayweather Promotions’ Leonard Ellerbe instructed reporters Mayweather “had no interest” in preventing Pacquiao soon after his battle in Japan past calendar year.
