Olympic wrestling medalist tests positive for meldonium

MOSCOW (AP) Sabotage is to blame for a string of recent failed doping tests for meldonium in Russia, the country's skating federation said Wednesday.

At least three Russian speedskaters have tested positive for meldonium, the same medicine found in Maria Sharapova's sample at the Australian Open.

''In our specific case, there is a very high probability, and we will prove it, that the banned substance was planted on three athletes deliberately,'' skating federation president Alexei Kravtsov said. ''According to our information, it was done by their teammates.''

Kravtsov did not name any suspects or say how the substance might have been given to them. He said the federation had tried to persuade police to investigate but had been turned down on the grounds that there was insufficient evidence that a crime had been committed.

Olympic short-track skating champion Semyon Yelistratov and reigning world sprint champion Pavel Kulizhnikov have failed doping tests for meldonium. Kravtsov later told Russian agency R-Sport that meldonium had also been found in a sample given by short-track skater Ekaterina Konstantinova.

Kravtsov said the federation had hired British lawyers to prove their innocence.

In separate cases, former European ice dancing champion Ekaterina Bobrova, volleyball player Alexander Markin and cyclist Eduard Vorganov are among Russian athletes who have reportedly tested positive for meldonium since it was banned Jan. 1.

The British Journal of Sports Medicine reported Wednesday that up to 490 athletes at the 2015 European Games in Baku were taking meldonium, when it was still legal.

Also, Olympic wrestling silver medalist Davit Modzmanashvili of Georgia has admitted to using meldonium and faces a possible life ban for a second doping violation.

Vakhtang Blagidze, a Georgia national wrestling team coach, said Wednesday that Modzmanashvili tested positive for the drug last month. The federation said another five members of the team tested positive for meldonium but their names have not been released because they deny the charge.

Modzmanashvili won the men's 120-kilogram silver medal in Greco-Roman wrestling at the 2012 Olympics. He also won world championship bronze in 2011.

The federation said that none of the six were confirmed to compete at the Olympics in Rio de Janeiro in August, but that qualification was still possible.
