GUANGZHOU - Another doping case has been confirmed at the Asian Games, according to an Olympic Council of Asia source on Wednesday.
The OCA source said the second doping case involved a wrestler from Uzbekistan who didn't win medal in Guangzhou.
The wrestler was caught for using the banned stimulant Methylhexaneamine, the source told Xinhua.
The men's wrestling competition started on November 21 and the women's will begin on November 25 Thursday.
In the Games' first doping case, Uzbekistan's judoka Shokir Muminov was stripped of his silver medal last Friday after testing positive for Methylhexaneamine.
The 27-year-old Muninov lost to South Korea's Kim Jae-Bum by ippon in the 81kg division final, while Japan's Masahiro Takamatsu and Islam Bozbayev of Kazakhstan shared third place.
Takamatsu and Bozbayev were raised to joint second and took silver medals last Saturday.
All samples collected at the Guangzhou Games are being tested at the WADA lab in Beijing, which conducted drug checks for the 2008 Summer Olympics.
Methylhexaneamine has been the subject of several high-profile doping cases since the WADA added the substance to its banned list this year.
Nigerian sprinter Osayomi Oludamola was stripped of her Commonwealth Games 100 meters gold medal for using Methylhexaneamine. Six Indian wrestlers and three swimmers also tested positive for the same drug ahead of the Games.
The substance is widely used as a nasal decongestant but is also found in recreational drugs. A component of flower oil, the substance is a common ingredient in a variety of nutritional supplements and easily available on the Internet.
Some athletes have said they unwittingly ingested Methylhexaneamine when using supplements or other products.
In last Asian Games in Doha, four weightlifters, including two Uzbekistan athletes, were disqualified for positive doping tests.
