Las Vegas, Nevada - WBC/WBA welterweight and junior middleweight champion Floyd Mayweather Jr. (47-0, 26KOs) has two more fights to go, according to unbeaten fighter himself. 

Mayweather, 38-years-old, has two fights remaining on his exclusive contract with Showtime/CBS.

He returns on May 2nd at the MGM Grand, where he faces WBO champion Manny Pacquiao (57-5-2, 38KOs) in a mega-fight pay-per-view event.

Mayweather plans to fight one more time, on September 12th, to satisfy his CBS/Showtime contract. After that, he plans to retire.

"There is one more fight. I'm honest. That's one thing about me, I'm honest. I'm pushed to a point where I don't get nervous by no fighter. I'm not moved by anything. I got one more fight and I'm out of my contract. I love being with Showtime and CBS, I couldn't thank them enough," Mayweather said.

When asked if he might stick around to headline the first boxing event at the new arena being constructed in Las Vegas - Mayweather said he would consider taking his last fight to the new venue - if the new venue is done by September.  MGM Resorts International and AEG are in the process of constructing a new 20,000 seat arena on the Las Vegas strip.

"My last fight is in September. If the new arena is done by September, I'll sit down with my team and see if we can go into the new arena - but the [MGM] Grand Garden is my home," Mayweather said.
