Attila Ungvari's 'B' sample tests positive

BUDAPEST, Hungary -- The Hungarian Judo Association says judoka Attila Ungvari's backup sample has confirmed his positive test for the steroid stanozolol.

Ungvari's samples were taken after he won gold in the 73-kilogram division at the World Cup in Budapest in February. The 22-year-old Hungarian also tested positive in January after a competition in Baku, Azerbaijan.

The association says it supports Ungvari's innocence, adding that the judoka and his coach passed polygraph tests confirming the athlete's claim that he ingested the illegal substances unknowingly.

Ungvari is a four-time national champion and bronze medalist at the 2010 European championships in Vienna. He is the first Hungarian judoka to fail a doping test.
