Amir Khan has indicated that his potential fight with Floyd Mayweather will not go ahead.
Khan claims that he signed a contract in December that put him in line for a possible fight with Mayweather this year, with Mayweather asking fans to vote on Twitter whether his next fight should be against the Bolton-born fighter or Marcos Maidana.
However, in a series of tweets on Friday, Khan revealed that he would not be fighting the Mayweather, who he implied would be taking on Maidana, who lost on points to Khan in 2011.
"No response from Mayweather or his team," wrote Khan. "Fight is not happening. I should of taken the title fight last December against Alexander...
"Very disrespected by his team. Wasted my time. Good luck to Maidana, against Mayweather.
"Can I apologize to the thousands of people who are let down. You, me and everyone wanted the Mayweather fight. He's running scared."
Khan, 27, has been holding out for a lucrative clash with Mayweather since suffering a scare in his dramatic points victory over Julio Diaz in Sheffield last April.
The Bolton man has a 28-3 record as a professional, while Mayweather has won all 45 of his bouts.
