Amir Khan has admitted that he is "disappointed" with Floyd Mayweather Jnr for delaying the announcement that the pair would not meet for a fight in May.

Reports suggested that an agreement between the two was close to completion but Mayweather confirmed earlier this week that he will now face Marcos Maidana in Las Vegas, leaving Khan to search for a new opponent.

"Despite having signed my part of the agreement to fight Floyd in early December, I've been preparing myself for some time that the match up with him wasn't going to happen, as I announced on Twitter a few days ago," Khan revealed in a statement on his website. "Therefore, this announcement did not come as a surprise.

"I am, however, very disappointed with Floyd and his team for not providing any explanation as to why he delayed the announcement for so long and ultimately avoided the fight with me.

"Clarification, if he was not fighting me, would have allowed me to look over my options and pursue another path, rather than the ultimate delay to my career this has caused."

Mayweather will be defending his 45-fight unbeaten record when he faces Maidana.
