Floyd Mayweather and Manny Pacquiao will face off in a professional rematch this September at the Sphere in Las Vegas. The bout will stream globally on Netflix, the fighters and promoters announced Monday.

This fight marks Mayweather's return from retirement and will be the first professional boxing match held at the Sphere.

Mayweather, with a perfect 50-0 record, defeated Pacquiao in their 2015 "Fight of the Century." That bout generated record pay-per-view buys and a significant live gate.

"I already fought and beat Manny once. This time will be the same result," Mayweather stated.

Pacquiao, holding a 62-8-3 record, expressed confidence in handing Mayweather his first professional loss.

The rematch will stream to Netflix's extensive subscriber base, continuing the platform's expansion into live boxing events.
