KARACHI, Nov 6 - Mohammad Asif has filed an appeal with the Pakistan Cricket Board (PCB) against the one-year ban imposed on him for a doping offence, he told Reuters on Monday.

"I have filed a written appeal through my lawyer with the board and hopefully it will prove successful," the cricketer said during a telephone call.

Fast bowler Shoaib Akhtar, who is banned for two years for the same offence, is yet to file an appeal, a PCB official told Reuters.

Both bowlers were banned last week by a drugs tribunal of the board after they were recalled from the Champions Trophy in India for testing positive for a banned steroid, nandrolone.

The tribunal, headed by barrister Shahid Hamid, banned them after ruling they could not prove their innocence.

A PCB official, who declined to be named, told Reuters that the new drugs appeals tribunal will be headed by retired judge Fakhruddin G. Ebrahim with former test player, Hasib Ahsan and the President of the Pakistan Sports Medicine Association, Dr Danish Zaheer.

"The tribunal will hear the appeal and should give a verdict within seven days," the official said.

In 1995 Ebrahim held an independent inquiry on behalf of the PCB into allegations made by Australian players Shane Wane, Mark Waugh and Tim May against former captain Salim Malik that he had offered them bribes in 1994 to perform below par.

The Justice acquitted Malik of all charges primarily on the basis of insufficient evidence after the Australians refused to come to Pakistan to testify before him.
