Retired former five division world champion Floyd Mayweather Jr. (49-0, 26KOs) said the "timing" was not right for a pay-per-view fight with British star Amir Khan (31-3, 19KOs).

Khan chased after Mayweather for several years, but he was always passed over in favor of other fighters.

In 2014, he was passed over twice in favor of Marcos Maidana. Mayweather won the first bout with Maidana decisively and there was little reason to face him again in the fall. Khan also holds a win over Maidana.

After Mayweather fought Manny Pacquiao in May of last year, many insiders assumed he would face Khan in the fall - considering the fighters who were in the running.

After weeks of speculation, Mayweather shockingly selected Andre Berto, who shares the same trainer as Khan. Berto was 3-3 in his last six fights and a huge underdog. Mayweather dominated the fight quite easily for a decision win.

Mayweather retired following his win over Berto. Khan is now set for a major fight on May 7th at the T-Mobile Arena in Las Vegas. He will move up to 155-pounds to challenge Saul 'Canelo' Alvarez for the WBC middleweight championship.

During a recent tour of the UK, Mayweather was hounded with questions on why he never gave Khan a shot.  

“It’s all about timing. A lot of people didn’t think that the Manny Pacquiao fight would happen but it did, so the timing wasn’t right to fight anybody else,” Mayweather told the Manchester Evening News.

“I’m now retired so I’m not interested in facing anybody else, my main focus is on promotional company Mayweather Promotions. It’s been great to tour the UK and touch so many people. I’ve met a lot of fans and they have welcomed me with open arms.”
