Olympians Adrian Zielinski and Silvia Danekova Just Tested Positive for Banned Substances

Two Olympians may have blown their chances at fame after testing positive for banned substances, Associated Press reported. Polish weightlifter Adrian Zielinski and Bulgarian steeplechase runner Silvia Danekova both reportedly tested positive for different banned substances.

Zielinski, a 27-year-old 2012 Olympic champion weightlifter, tested positive for the anabolic steroid nandrolone, Poland's anti-doping committee said, according to Agence France-Presse. He'd been planning to compete in the men's 94 kg event before news broke that both he and his brother, 25-year-old Tomasz, had tested positive for steroids.

Danekova, who competed in the steeplechase run at the 2012 Olympics, tested positive for a banned blood-booster called erythropoietin, Reuters reported. Erythropoietin, or EPO, is used to increase the rate of red blood cell production in the body. Danekova was suspended, pending the result of her B-sample, according to Reuters.

Earlier this month, multiple Russian athletes were kicked out of the Olympics amid doping allegations, though many argued for a blanket ban for Russia's competitors. On Sunday, Chinese swimmer Chen Xinyi tested positive for a banned diuretic called hydrochlorothiazide, the BBC reported. The 18-year-old Olympian has reportedly been suspended while the allegations are investigated.
