Here's a date to keep in mind for those of you still holding what little hope there is for a Manny Pacquiao-Floyd Mayweather match or just hate seeing Mayweather win all the time: Sept. 2015. That's the month the undefeated champion says he's going to retire.

Mayweather made the announcement during a gala at South Africa, and he said he has about four fights left in his career. That would bring his record to 49-0 if he went on to win. His next fight is this May, and possible contenders include Marcos Maidana (the man who beat Adrien Broner and made a meme out of him) and Amir Khan.

Mayweather has been fighting professionally since 1996 and is considered one of the greatest alive after almost two decades with of epic shit-talk and dominance.
