Floyd Mayweather might be thinking harder about coming out of retirement than he is letting on.

Mayweather told Showtime on Saturday that while he’s happy to be retired, he has “been talking with CBS and Showtime” about a potential return, “and you never know.” He said he was discussing guarantees that would top $100 million if he returned.

Mayweather Productions filed for trademarks to “TMT 50” and “TBE 50” on April 21, ESPN.com has learned. Records recently posted on the U.S. Patent and Trademark website confirm the filings.
