Floyd Mayweather has announced that he is likely to retire in September next year, but says rumours of a potential super-fight with Manny Pacquiao are "not true".

The undefeated pound-for-pound king told reporters that he will call time on his stellar career at the end of his six-fight, $200million deal with Showtime/CBS, which has three more fights to run. The first of those takes place on Saturday, a welterweight world title rematch against Marcos Maidana, with another fight likely next May and then again in September.

"I only got two more fights left [after Saturday] and after the next two fights I just want to build the Mayweather Promotions brand," the 37-year-old told reporters on Tuesday night.

Mayweather, who has retired for brief spells twice before, typically fights in May and September each year and sees no reason to change that schedule in 2015.

"My next fight is in May and my last fight is in September, so a year from now will be my last fight.

"As of right now, my focus is on Maidana. I can't focus on the other two fights after that. I have to focus on Maidana. After that we can't say who's the next two are going to be but I'm pretty sure the next two will be exciting fights."

One, or even both, of those fights have been rumoured to be against long-time rival Manny Pacquiao. A super-fight with the Filipino is again a topic of huge conversation after Pacquiao’s promoter Bob Arum suggested that the pair, who have been in and out of negotiations for years, could fight twice next year with a ‘double-or-nothing’ rematch.

But Mayweather has said there is no truth to Arum’s claims.

"Not true," Mayweather said of the rumours. "I can't say what the future holds, but Arum and Pacquiao is trying to sell tickets for the [fight with the] guy named [Chris] Algieri. I don't know where they fighting, I don't know anything about what Top Rank is doing."
