"I have filed my appeal through my lawyer, Aftab Gul, and submitted it to the PCB's medical officer, Doctor Sohail Saleem, and I hope my ban will be reviewed by the appeal committee," Asif told AFP.

A PCB tribunal last week banned Asif for one year and fellow paceman Shoaib Akhtar for two years after the pair tested positive for the banned steroid nandrolone.

The tests were conducted in September and once the results were known, in mid-October, the PCB suspended the pair, pulling them out of the Champions Trophy in India.

The ban also means both are ruled out of next year's World Cup in the West Indies.

The PCB had already announced a two-man appeal committee comprising former High Court judge Fakhruddin Ibrahim and former Test cricketer Haseeb Ehsan.

Asif's lawyer, Gul, is a former Test opener who played six Tests for Pakistan between 1969 and 1971.

"This is a case of mitigation and we have questioned the quantum of sentence to our client," Gul told AFP.
