According to a report by ESPNcricinfo, the International Cricket Council informed the PCB about the matter, prompting the board to initiate formal proceedings. The outcome of the process is expected to be communicated to the ICC shortly.
The positive test reportedly dates back to the T20 World Cup earlier this year in Sri Lanka, where the 32-year-old featured in all seven matches for Pakistan, scoring 15 runs and taking seven wickets as the team exited in the Super Eight stage.
Nawaz had been set to play the entire Vitality Blast season for Surrey from May 26 to July 18, with the PCB previously granting him a no-objection certificate. However, the deal has now been terminated.
He is currently representing Multan Sultans in the Pakistan Super League and recently went wicketless in a match against Rawalpindi despite bowling three overs.
