Russian combat sambist Artur Poleyan has been banned for four years after he tested positive for a banned substance.
The Russian Anti-Doping Agency (RUSADA) confirmed the sanction against Poleyan, who has been suspended from October 19 of last year.
Poleyan will be unable to return to competition until October 2024.
He won the gold medal in the over-98 kilograms combat sambo category at the 2020 Russian Sambo Cup in Kstovo, held from October 2 to 4.
Poleyan defeated Gadzhi Omaraov in the final of the competition and looks set to keep his title from the event, despite testing positive for a prohibited substance or its metabolites.
"The All-Russian Sambo Federation, following the decision by Disciplinary Anti-Doping Committee RAA RUSADA, rendered the decision that made athlete Artur Poleyan ineligible for four years for violation of art. 2.1 of the All-Russian Anti-Doping Rules, the period commencing on October 19, 2020," RUSADA said in a statement.
