When you're undefeated it may seem like you can go on fighting forever -- but in the end Father Time always wins. 

Floyd Mayweather announced that after his rematch with Marcos Maidana this weekend he'll only be fighting two more times before he calls it quits. 

"I only got two more fights left [after Saturday] and after the next two fights I just want to build the Mayweather Promotions brand," Mayweather said, according to ESPN. "My next fight is in May and my last fight is in September, so a year from now will be my last fight."

If Mayweather remains undefeated over his next few bouts he'll be one win shy of 50. Should Floyd bow out at 49 professional wins or should he continue until he hits the big 5-0? Let us know your thoughts below.
