Floyd Mayweather says he will fight Manny Pacquiao again this year

Floyd Mayweather Jr. will unretire for the fourth time to fight Manny Pacquiao in a rematch of their much-hyped 2015 fight in December.

Mayweather announced on Instagram Saturday, saying, "I'm coming back to fight Manny Pacquiao this year another 9 figure payday on the way."

The unbeaten Mayweather (50-0, 27 KO's), 41, who held world titles in five different weight classes and the lineal championship in four weight classes, made about $220 million from his May 2015 fight with Pacquiao (60-7-2, 39 KO's), who earned about $180 million.

Pacquiao, who is also a Senator in his native Philippines, will turn 40 years of age on Dec. 17.

Mayweather and Pacquiao were seen talking to each other at what appears to be an electronic music festival in Tokyo. Most of the conversation is difficult to understand because of the music, but we were able to grab one essential part of the discussion.

"He said we're gonna be easy," Mayweather said to the people behind him" to which Pacquiao responds, "I have the belt. I have the belt! I have the belt."

"The belt!?" Mayweather laughed. "I'm going to take it from you like I did before!"

"Hey! I don't want no shoulder excuses," Mayweather added.

Mayweather defeated Pacquiao by unanimous decision in their first fight, while Pacquiao blamed his performance on an injured right shoulder.

Since facing Pacquiao, Mayweather also scored victories against Andre Berto in September 2015 and his August 2017 knockout of former UFC lightweight champion Conor McGregor in the latter's professional boxing debut.

Pacquiao last fought in July, knocking out Lucas Matthysse in the seventh round to win a secondary welterweight title. The Filipino superstar called out Mayweather for a rematch after the win.
