The Bulgarian weightlifter Boyan Polejanov has tested positive for steroids.
Polejanov, who finished seventh in the +105 kg category at the European Championships in Minsk in April, tested positive for the banned anabolic substance methandienone.
The 25-year-old has denied any wrongdoing but announced he would retire and not seek a B sample test.
The Balkan country withdrew its team before the start of the 2008 Olympics in Beijing after 11 members failed doping tests and missed last year's world championships due to financial problems.
