The Pakistan cricketer Mohammad Asif may face a two-year ban after his B sample tested positive for the steroid Nandrolone.
It's the latest in a series of controversial incidents which have dogged the 25-year-old fast bowler's career over the past couple of years.
Asif, who has denied taking any banned substances, also tested positive for Nandrolone in 2006 along with fellow paceman Shaob Akhtar.
Asif also faces a ban or fine from the PCB after he was detained in Dubai for possession of illegal drugs, and held for 19 days before he was deported.
