Zoltan Kovago, who won a silver medal in the discus throw in 2004, had a doping violation appeal tossed out by the International Court of Arbitration for Sport and will be barred from the 2012 Games.
Kovago was originally acquitted by Hungarian anti-doping officials but the international track federation appealed. Thursday the CAS upheld a two-year ban against Kovago.
Also Thursday, the father of Greek high jumper Dimitrios Chondrokoukis said his son had a positive result on a doping test. Chondrokoukis is reportedly seeking a retest.
Chondrokoukis is the reigning world indoor high jump champion.
Nine other track and field athletes on Wednesday were found to have violated anti-doping measures. They are from Bulgaria, Greece, Morocco, Russia, Turkey and Ukraine.
Greece on Wednesday said triple jumper Paraskevi Papachristou was removed from the country's Olympic team because of a racist comment on her Twitter account. Papachristou apologized for what she termed an "unfortunate and tasteless joke."
