A Pakistan cricketer has reportedly tested positive for a banned substance, although his identity is yet to be confirmed by the Pakistan Cricket Board.
The PCB revealed the news via a single tweet this morning, but said it was not yet able to reveal the name of the player.
The name of a player, and the substance he's alleged to have tested positive for, has been shared on social media although that rumour has not been confirmed.
Cricketers can be banned for up to two years if found guilty of taking banned substances, depending on the nature of the case.
Afghanistan wicketkeeper-batsman Mohammad Shahzad was handed a 12-month backdated ban last year after returning a positive test for clenbuterol, with his sentence lessoned after the ICC accepted that he'd inadvertently ingested the prohibited substance as part of a weight-loss product he was taking.
In 2016, Pakistan spinner Yasir Shah was banned for three months after he tested positive for chlortalidone. The ICC ruled that Yasir had inadvertently taken his wife's blood pressure medication, which contains chlortalidone, and gave him a lighter sentence.
In 2015, Pakistan spinner Raza Hasan returned a positive test for cocaine and was banned for two years.
