Pakistan all-rounder Mohammad Nawaz is under investigation by the Pakistan Cricket Board (PCB) after returning a positive test for recreational drug use, according to a media report on Wednesday.

The 32-year-old left-arm spinner, currently playing for Multan Sultans in Pakistan Super League (PSL) 11, was reportedly flagged during testing conducted at the ICC Men’s T20 World Cup earlier this year.

A PCB spokesperson confirmed that the matter is under review following formal communication from the International Cricket Council (ICC).

“The ICC has informed the PCB about this matter, and the board has begun due process. The outcome will be communicated to the ICC,” the spokesperson said.

The ICC has not issued a public statement on the case.

Reports indicate that the sample in question was taken during the global tournament, where Nawaz played all seven matches for Pakistan.

He scored 15 runs and claimed seven wickets as Pakistan exited the competition at the Super Eight stage.

The investigation comes as Nawaz continues to feature in PSL 2025, raising questions over his immediate availability depending on the outcome of the inquiry.

The development has also affected Nawaz’s planned participation in England’s T20 Blast. His proposed deal with Surrey County Cricket Club has reportedly been cancelled following the positive test.

Nawaz had earlier secured a No-Objection Certificate (NOC) from the PCB and was expected to feature in the tournament, scheduled from late May to mid-July. However, Surrey opted not to proceed with the signing. The county has declined to comment.

The case places Nawaz under scrutiny at a crucial time in the PSL 11 season, with the PCB’s findings likely to determine any further action.
