Khan, 27, recently told media in Dubai that his side of a deal to fight the pound for pound king was signed, although Mayweather has now been quoted by Fighthype.com disputing these claims.
In a five-point argument, Mayweather outlined the main points as to how Khan can say the deal is done, although stopped short of actually confirming that the fight will not happen.
The 36 year-old still remains an odds-on to share a ring with Khan at the MGM Grand in late spring, but does seem to be getting somewhat tired of constantly correcting rumours surrounding his next fight.
It’s not thought that there are any other fighters than Khan in the frame for Mayweather’s 46th pro outing after second favourite Marcos Maidana’s advisor Sebastian Contursi stated that no contact had been made when speaking to WBN recently.
Mayweather is expected to make a formal announcement this month on who he will face in what will be his third instalment of a six-fight deal with Showtime – as Khan lines up to make his welterweight bow against the best around.
