Floyd Mayweather has selected his opponent for his upcoming May 4 fight, and an official announcement will come soon, according to a report from Rick Reeno at BoxingScene.com.

Mayweather (43-0, 26 KO) seems likely to face Robert Guerrero (31-1-1, 18 KO) for the WBC welterweight title. Mayweather holds the full title, while Guerrero has the interim belt.

Richard Schaefer of Golden Boy Promotions says that despite any rumors to the contrary, Timothy Bradley has not been in the running to face Mayweather:

"That is not correct. If that is what [Top Rank] are telling Timothy Bradley, then they are misleading Timothy. ... There have been zip, zero conversations related to that. We know that Top Rank likes to throw around Floyd Mayweather's name. They've done it for years with [Manny] Pacquiao."

Mayweather-Guerrero has been the expected fight for a while now, but a supposed early January date for an announcement of the fight has come and gone. It's also not certain that Canelo Alvarez will be in the co-feature on the HBO pay-per-view, though the idea is legitimately in play.

Schaefer says that contracts for the Mayweather bout are currently being finalized.

Whatever Mayweather does on May 4, it will be one of the true big nights for the sport yet again, as Floyd has really not lost any marketability and now stands as clearly the biggest and best fighter in the sport in the minds of the general public.
