According to newspaper reports here, even though the unnamed player did not test positive for drugs but admitted to an "incident occurring and was subsequently counselled".
"The player did not test positive for the drug and was not subject to Cricket Australia's formal drugs policy," reported 'The Australian'.
Cricket Australia, on its part played down the reports.
"Cricket Australia confirmed today that no current Australian, State or BBL player has tested positive or breached CA's anti-doping or illicit drugs policies," CA said in a statement.
"Noting a newspaper report claiming a cricketer has been counselled on an alleged illicit drugs issue, CA said that in common with other employers, it deals from time to time with employee welfare issues.
"CA's policy dealing with player welfare issues is to do so in a confidential, medically-based manner," it added.
