Australian spinner Shane Warne has failed a second test for a banned substance.
Warne now faces a two-year ban
The 33-year-old will appear before the Australian Cricket Board's anti-doping committee on Friday morning and faces a possible two-year ban if found guilty of a doping offence.
Warne, who is his country's leading wicket-taker in Tests and one-day internationals, withdrew from the Cricket World Cup last week after announcing his A sample had tested positive for a banned diuretic.
An Australian team source has now told BBC Sport that Warne's B sample has also tested positive.
The leg spinner has insisted he took a fluid-reducing tablet given to him by his mother last month without knowing it contained a banned substance.
Warne will go before a three-man hearing on Friday. Justice Glen Williams, of the Queensland State Court of Appeal, will chair the ACB anti-doping committee, with former Test off-spinner Peter Taylor and medical specialist Susan White completing the panel.
The hearing will be at the ACB's headquarters in Jolimont and will start about 2130 local time.
Warne had expected the World Cup to be his swansong after announcing he would quit one-day cricket once the tournament was over.
But if he is banned for two years, it would likely signal the end of his international career.
