The 26 year-old from Bolton had originally looked to return in the US this December, although a deal with Mayweather would take precedent as Khan bids to land the biggest challenge of his career so far.
“We are still in negotiations with Mayweather and it could be next or one fight after that,” Khan told Sky Sports in Atlantic City.
“If we could bring it to the UK it would be amazing and give the UK fans the chance to see a huge fight. To get Mayweather to come to the UK would be massive. It would be the biggest fight ever in the UK and I am really going to try for that.
“An announcement could be made in a couple of weeks or a couple of months,” he added.
Mayweather, 36, recently dismantled mandatory challenger Robert Guerrero in Las Vegas and has a date in September set aside for his return. ‘Money’ has always stated his intention to one day fight in the British Isles and Khan’s move up to welterweight could now see the clash become a reality, certainly in the next twelve months.
