Greece's world indoor high jump champion Dimitris Chondrokoukis withdrew from the London Olympics yesterday after testing positive for the drug Canadian sprinter Ben Johnson used before the 1988 Seoul Games.
Johnson was sent home in disgrace after metabolites of the anabolic steroid stanozolol were found in his urine sample following his victory over Carl Lewis in the 100 metres final in world record time.
Chondrokoukis' father and coach Kyriakos says the athlete will seek a retest after a positive test for stanozolol.
Hungarian discus thrower Zoltan Kovago, a silver medallist at the 2004 Athens Games, will also miss the Olympics after the Court of Arbitration for Sport said he had failed to provide a sample when requestedm, which Kovago has denied.
Another medallist from this year's world indoor championships, Moroccan 1,500 metres silver medallist Mariem Alaoui, will miss the Games after a positive test for a banned diuretic.
On Wednesday the world athletics governing body also announced that nine track and field athletes had been banned for doping violations.
