ATHENS, Greece (AP) -- A Greek race walker will miss the Sydney Games for steroid use, and a cyclist could be left off the Olympic team depending on the outcome of another drug test.
Alexandra Tziouti, who holds Greece's 10-kilometer walk record, was excluded from the Olympic team because she twice tested positive for nandrolone.
Cyclist Giorgos Himonetos tested positive for the steroid stanozolol. His Olympic participation will depend on the result of the second urine test Tuesday at a state-run laboratory.
"If that test is positive again, he will also be excluded from the Olympic Games," said Yianni Papadoyiannakis, head of Greece's Olympic squad.
Athletes found guilty of using banned substances can be suspended for up to two years.
Papadoyiannakis, also deputy chairman of the Greek Olympic Committee, said Tziouti contended she took the substance because she has osteoporosis. Himonetos cited therapeutic reasons.
"Our standing policy is for an anti-doping test on all athletes prior to the Olympics," Papadoyiannakis told the newspaper Ta Nea.
Papadoyiannakis said 146 Greek athletes -- 91 men and 55 women -- so far have qualified for the Olympics.
