However Khan’s promoter Frank Warren revealed tonight his counterpart Don King has confirmed the Mexican has been cleared to go ahead with the MEN Arena show following a “thorough medical examination”.

“It’s a great relief to finally get confirmation that Barrera will be ready for March 14,” said Warren, who has already sold 15,000 tickets for the contest.

“Sometimes these problems happens in boxing and you have to get through them, but I’m delighted that the fight is on and now we can get back to business and sell the remaining tickets for what will be a great fight.”

Khan, who is currently undergoing a training camp in Los Angeles with coach Freddie Roach, added: “It was a worrying few days but it’s great news to hear that it’s still on the original date.

“I was never worried that the fight wouldn’t happen, at the worst it would have been delayed by a couple of weeks, but now my team are all geared up and ready for March 14.

“My training camp is going absolutely fantastic and I will be in the best shape of my life come fight night.”

Barrera had been facing Rojas in a warm-up bout in Mexico in which he was headbutted and cut in the third round by the Cuban, who was then disqualified.
