Boxing greats Manny Pacquiao and Floyd Mayweather have agreed a professional rematch in September.

Pacquiao, 47, and Mayweather, 48, will fight at Sphere in Las Vegas on Saturday, 19 September, with the bout live on Netflix.

Former world champion Mayweather announced he would come out of retirement for a fourth time last week.

It will be the American’s first professional fight since beating mixed martial arts fight Conor McGregor with a 10th-round technical knockout in 2017.

Filipino Pacquiao retired from the sport to focus on his political career in 2021 but returned to the ring last July to fight WBC welterweight champion Mario Barrios, who retained his title after a draw.

Mayweather and Pacquiao first met in 2015, in what was billed as the ‘Fight of the Century’ and remains the richest in boxing history.

It was Mayweather who emerged victorious, beating Pacquiao via a wide unanimous decision in Las Vegas.

It is not yet known over how many rounds or at what weight class the rematch will be contested.

Pacquiao, winner of 12 world titles across eight weight classes, said: “Floyd and I gave the world what remains the biggest fight in boxing history.

“The fans have waited long enough. They deserve this rematch.

“I want Floyd to live with the one loss on his professional record and always remember who gave it to him.”

Mayweather, who turns 49 on Tuesday, said: “I already fought and beat Manny once. This time will be the same result.”
