A Malaysian athlete, widely reported to be badminton world number one Lee Chong Wei, will find out the results of a second doping test next month after a first test came back positive, the country's sports minister said on Saturday.
Malaysian sports minister Khairy Jamaluddin told a newspaper that a national athlete had tested positive for a banned substance in an international tournament.
Authorities have refused to identify the athlete pending the second test.
We are going through the athlete's recent medical history to see how the substance could be present
But media have widely named him as the top shuttler, with Malaysians expressing shock and disbelief at the allegations Lee failed a random test after the semi-finals of the world badminton championships in Denmark in late August.
Lee has not commented on the claims.
Khairy was quoted by The Star as saying the athlete in question had been given a choice of two dates - November 4 and 5 - for a second sample to be tested.
The athlete reportedly wants to be present at the laboratory in Oslo when the sample is opened. Results typically take four to five days.
