Mr Khan, 34, said he had been taken off the American Airlines plane along with a colleague by police when someone complained his friend's mask "was not high enough".

The airline said the flight from Newark Airport to Dallas-Fort Worth returned to the gate after two people reportedly "refused to comply with crew requests".

It denied that police had intervened.

But the 34 year old Liverpudlian admitted that an offer for one further fight could be too lucrative to turn down.

"I don't know how many times more I can put my body and family through this," Bellew told the BBC.

Asked whether the Haye bout would be his last, he added: "It's an option. It's something I'm thinking about."

WBC cruiserweight champion Bellew defied most predictions to beat Haye, who was affected by a torn Achilles tendon, on his heavyweight debut, and he now has 29 wins and a draw from 32 fights.
