If they were any other 49- and 47-year-olds, the medical scrutiny might be far more intense.

But as Floyd Mayweather Jnr and Manny Pacquiao are expected to clear that hurdle with minimal stream ahead of their rematch later this year. 

“Floyd’s always in shape and is [routinely] in the gym,” one individual connected to the matter told BoxingScene Tuesday.

Mayweather, 50-0 (27 KOs) and Pacquiao, 62-8-3 (39 KOs) are due to meet atop a September 19 Netflix event from The Sphere in Las Vegas. It will mark the first-ever boxing event at the state-of-the-art venue.

Their rematch follows their 2015 meeting that still stands as the most lucrative prize fight in history, with a record 4.6 million pay-per-view buys and more than $600 million in revenue. Mayweather won via unanimous decision to solidify his longtime place as the sport’s pound-for-pound king.

Just two pro fights followed for Mayweather, none since his August 2017 crossover fight with UFC champion Conor McGregor. His prior fight was a 2015 decision over former titleholder Andre Berto.

Pacquiao fought in Nevada last year, fighting WBC welterweight champion Mario Barrios to a draw in July, his first fight in nearly four years. Based on that showing and some other information, the Nevada Athletic Commission licensed him for 2026 at its February meeting.

BoxingScene has learned Mayweather’s reputation for year-round fitness will likely require light examination by the commission, likely just a cursory observation of his sparring at the Las Vegas-based Mayweather Boxing Club.

Those connected to the bout on Netflix said they expect the fighters to again earn more than $100 million each.
