WBA 'regular' welterweight champion Keith Thurman (26-0, 22KOs) has no doubt that Floyd Mayweather Jr., the WBC/WBA super champion at 147-pounds, will fight beyond his September 12th return date at the MGM Grand in Las Vegas. Mayweather claims the September fight is his final bout as a pro.

Mayweather is likely facing former WBC/IBF welterweight champion Andre Berto in the main event of a Showtime Pay-Per-View. The fight is also Mayweather's last contractual obligation under his exclusive Showtime/CBS agreement.

Thurman feels Mayweather is just running out his SHO/CBS contract and then will have full control of his future fight options.

"I don't think he's going to retire on an Andre Berto. I never assumed he was going to retire. The one thing that's up his Showtime contract. Just because the contract is up, doesn't mean his career is cover. It is always going to be optional for Floyd for how many more steps, how many more fights he wants to go, how long he wants to journey throughout the world of boxing in the future," Thurman said.
