Athens - Weightlifter Ferenc Gyurkovics of Hungary has failed a drug test and risks losing his Olympic silver medal, a national Olympic committee spokesperson said on Friday.
The International Olympic Committee scheduled a disciplinary hearing for later on Friday for Gyurkovics, who competed in the 105kg class.
The Hungarian Olympic Committee plans to ask the IOC to have his backup sample tested by an independent laboratory, spokesperson Dezso Vad said.
Gyurkovics set an Olympic record by lifting 195 kilograms in the snatch on Tuesday, but wound up finishing second to Dmitri Berestov of Russia in the overall totals.
Four medals already have been overturned at the Athens Games for doping violations.
Meanwhile Hungary's Olympic hammer throw champion Adrian Annus has been found by doping testers and given a deadline to provide a new urine sample, the president of Hungary's Olympic Committee said on Friday.
Pal Schmitt, head of the Hungarian Olympic Committee, said the deadline for Annus to give the sample initially was set for noon on Friday Hungarian time, but he later said it had been extended for several hours, and would not be specific.
Annus, now in Hungary, passed a drug test after winning the hammer throw on Sunday, but doping control officials have been trying to track him down since then for further testing.
The IOC wants to find out whether he provided his own urine for the test or whether he tried to beat the screening system, as team-mate and discus gold medallist Robert Fazekas allegedly did.
Fazekas lost his gold medal after Olympic authorities said he failed to provide enough urine for a drug test, a charge Fazekas disputes.
"I presume if he fails to comply with all the rules and regulations of the doping code the medal will be withdrawn," Schmitt said of Annus.
Annus retired on Thursday, but he remains under the jurisdiction of IOC doping rules until Sunday, the end of the Games. If found guilty of a doping offence by then, he would also lose his medal.
IOC president Jacques Rogge said on Friday that Annus will be subjected to out-of-competition testing.
"The IOC has asked the national Olympic committee to notify the whereabouts of the athlete in Hungary. We are waiting for these addresses," he said.
Without specifically referring to Annus, he said the IOC can use DNA tests to see if urine samples match.
"This is something we have in our weaponry. We didn't need it at this stage, but we have it and it might be used in the future," he said.
