Golden Boy Promotions CEO Richard Schaefer advised that Adrien Broner's decision to exercise a rematch clause, has removed Marcos Maidana from the list of possibilities for Floyd Mayweather's scheduled return on May 3rd at the MGM Grand in Las Vegas.

Mayweather has yet to name an opponent, but Maidana was viewed as a frontrunner, along with British superstar Amir Khan, to face Mayweather in May.

On Friday, Broner unexpectedly exercised his option for an immediate rematch with Maidana, which Schaefer plans to stage on April 19 or April 26. Broner hopes to avenge last month's unexpected unanimous decision loss to Maidana, where the Argentinian puncher scored two knockdowns and dished out punishment in numerous rounds.

While Maidana is no longer a possibility for Mayweather in May, the pound-for-pound king is also planning to fight in September - which opens up the door for the fight to get revisited - if both boxers win their upcoming ring appearances.

"Well, it obviously appears as such [that Maidana is no longer viable for Mayweather in May], but as we all know Floyd is planning on fighting twice this year, so there are going to be other dates available," Schaefer told

Schaefer is keeping a tight lid on giving any hints regarding Mayweather's potential opponent in May, although most view Khan as the solid favorite to land the fight.
