Sri Lankan opening batsman Upul Tharanga has been suspended for three months after failing a doping test, the International Cricket Council said on Friday.
The ICC said the 26-year-old left-hander's urine sample, taken after this year's World Cup semi-final against New Zealand in Colombo on March 29, contained prednisone and prednisolone which are on the World Anti-Doping Agency's banned list.
Tharanga pleaded guilty to the offence at an early stage in the proceedings, it added.
A three-member independent tribunal, chaired by Tim Kerr, accepted that the opener had ingested the substances when drinking a herbal remedy for a long-standing shoulder injury.
"It also found that Tharanga had no intention to enhance his sporting performance or to mask the use of another performance enhancing substance, but that he had failed to satisfy the high levels of personal responsibility implicit upon him as an international cricketer subject to anti-doping rules," read a statement from the ICC.
The tribunal used its discretion to back-date Tharanga's suspension, which started on May 9 and expires on Aug. 8, from all cricket-related activities.
"I apologise to the fans and followers of Sri Lanka cricket for inadvertently committing an offence," Tharanga was quoted as saying in the statement.
"I hope my fellow sportsmen will learn from my experience and be more vigilant when taking medical treatment, so that their careers do not suffer in the way that mine has."
Tharanga has 21 days to appeal against the decision.
"We recognise that Upul has not been found guilty of deliberately cheating, but the ICC maintains its zero-tolerance approach towards doping for the benefit of all its stakeholders," ICC chief executive Haroon Lorgat said.
"Cases like this serve as a reminder to all players that they must take great care and personal responsibility at all times for the substances that they consume.
"I am satisfied with the tribunal's decision and pleased at the way the ICC has handled this case with both sensitivity and efficiency."
