Khan had been due to contest the ABA quarter-finals

Khan's father, Shajaad, told BBC Sport the organisers were only offering 10 tickets to Khan's boxing club for the event in Great Yarmouth.

"It's a joke that we've only been offered 10 tickets," said Shajaad.

"He's won three fights since the Olympics and he's got nothing left to prove in this event."

BBC Radio Five Live boxing correspondent John Rawling believes Khan's withdrawal may be a smokescreen ahead of him turning professional, possibly with promoter Frank Warren, after one final amateur fight at a fundraising event.

But Khan's father insisted the current dispute would not affect his son's boxing status.

"He's not going to turn professional because of this, not for the moment anyway," he added.

How can we keep that amateur status? Khan's manager Asif Veli

Khan's manager Asif Veli warned the ABA that it should do everything in its power to prevent British boxing's hottest prospect from turning professional.

Khan said he planned to stay amateur in order to fight for gold at the 2008 Olympics in China.

But Veli said: "Beijing is a long, long way away. We're going to get massive hurdles and hurdles like this we have to overcome.

"And if we don't get the support from the governing bodies, how can we continue supporting the ABA at an amateur level when there is so much press interest in Amir Khan. How can we keep that amateur status?

"It's a two-way thing. They've got to work with us and we've got to work with them."

It should be a very simple issue to solve and I'm sure we'll solve it ABA spokesman Ron Bodie

Khan was due to fight James Martin in the quarter-finals of the ABA Championships at the 800-capacity Ocean Room.

The light welterweight had twice fought in front of large crowds at Liverpool's Olympia and at Preston's Guildhall in his previous three bouts. Valie said it was "ridiculous" for Khan to fight at a venue that held only 800.

"When he fought in December, 2,000 people were there at the Olympia - they packed it out," added Vali.

"He then fought at the Preston Guildhall and there were nearly 3,500 people there.

"He fought at the Olympia again and there were 2,400 people. Going down to 800 is a ridiculous situation. Unfortunately, the pressure is not on me, or the ABA, the pressure is on Amir to deliver."

ABA spokesman Ron Bodie hoped that the ticket issue could be resolved amicably.

"Amir needs to buy 'x' number of tickets for his immediate family and at the moment they're only allocating him 10 tickets to buy," Bodie told BBC Sport.

"It should be a very simple issue to solve and I'm sure we'll solve it."

The Kingfisher ABC club, which is hosting Saturday's event, said it had considered changing location, but instead opted to remain at the Ocean Club.
