Pakistan's suspended pacer Mohammad Asif is trying to engage sports medicine expert Dr Graham Durgan to appeal for him.

The medium pacer's lawyer Shahid Karim said on Wednesday that efforts were being made to appoint Durgan as he has the experience of helping athletes who have failed similar dope tests in the United Kingdom.

"Nothing is final as yet. But we are holding talks to secure the services of Dr Durgan," Karim said.

Asif earlier had also tried to hire famous British lawyer and anti-doping legal expert Mark Gay who has represented top class athletes on doping charges but he did not respond to the offer made.

Asif's lawyer has asked the IPL to postpone the B sample testing to be held in Switzerland at a World Anti-Doping Agency accredited laboratory since there are some visa related issues and he also requires some more time to prepare the case for the defence of his client.

Karim said they had sent in two requests to the Indian Premier League governing body but the IPL has neither accepted nor rejected their point of view.

Asif's legal counsel also said that in the worst case scenario if the IPL didn't accept their request, the B sample test would be held most probably without their presence.

The Pakistan board has already made it clear that it would not be offering Asif any assistance in the case and he has to fight it himself.

The board's medical commission member Dr Sohail Saleem, meanwhile, has also pointed fingers on Asif for the muddle he is in. He also said that Asif failing the dope test would not tarnish the image of Pakistan cricket.

"I don't think so because doping offences are the sole responsibility of an individual. Asif is responsible if he has failed a dope test in the IPL, not the board, and I don't think his actions reflect on our cricket," Saleem said.

He also made it clear players were being sufficiently educated in anti-doping laws and regulations and also said that the board is planning soon start doping tests even at the domestic level to avoid such incidents in the future.

"We have worked out a plan under which the board will soon introduce in-competition tests at first-class level. After appointing physios in all the regions we are now introducing dope tests in first-class matches, in-competition tests," he said.
