LONDON, July 26 (UPI) -- A medal-winning discus thrower from Hungary and a Greek high jumper are the latest athletes to be ensnared in doping issues at the London Olympics.
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.
