As per the rules, the opening batsman is set to be suspended from global cricket for a period of three months.
"But under ICC rules, PCB can not name the player or chargesheet him until the chemical report is CONFIRMED by the Anti-Dope Agency of the government". The PCB source said that as per the WADA and ICC anti-doping regulations, random dope tests were carried out regularly in domestic cricket as well.
According to sources privy to the matter, the 26-year-old cricketer from Lahore has failed the dope test, which may result in his immediate suspension.
In a press statement, PCB said "a player has reportedly tested positive for a prohibited substance".
PCB had heard the news during a meeting for the selection of Pakistan squad for the upcoming Zimbabwe tour.
It was learned that the PCB has made a decision to not consider Shahzad for selection for the upcoming tour. Sources close to Geo News have known that World Anti-Doping Agency has been informed and is expected to take an action.
