The Rugby Union of Russia has confirmed that meldonium traces were found in the doping tests of two athletes from Russian rugby-7 national teams, the federation said on its official website.
The names of the athletes have not been disclosed.
"A member of the men's rugby-7 national team accepted the positive results of the probe of his 'A'sample, refusing to see the 'B' sample opened. A member of the women's rugby-7 national team denies having taken any prohibited drugs or substances and is going to request for opening the 'B' sample in due order," the federation said in a statement.
"The both athletes have been suspended from competing at the events held by the Rugby Federation of Russia in rugby, rugby-7, and beach rugby, starting on February 4 (for the male athlete) and on February 26 (for the female athlete)," it said.
A working commission has been formed to investigate into the cases where the banned substance was used, according to the federation.
"Acting jointly with the WORLD RUGBY anti-doping department, the commission is currently investigating into these violations committed by the Russian athletes, rugby players," the federation said.
In the meantime, a source close to the Rugby Union of Russia told Interfax on Friday that Alyona Mikhaltsova and Alexei Mikhaltsov tested positive for meldonium.
