Dilshod Nazarov, Tajikistan, has been suspended by the International Athletics Association. The reason is that an eight-year-old doping test showed traces of a banned steroid, writes various foreign media.
The test was taken at the Korean Athletics Championships in Korean Daegu 2011, where he finished eleven.
Nazarov's main advantage came in 2016 when he took Olympic gold in hammers. He also has four golds from the Asian Championships, the last of which came in April in Doha - where the World Cup starts on Friday.
