Double world champion and two-time Olympic silver medallist Andrei Rybakov of Belarus has tested positive for banned substance meldonium, the International Weightlifting Federation (IWF) has announced.

Rybakov finished second in the under 85 kilogram category in the Olympics at Athens 2004 and Beijing 2008 and clinched the world titles in the division in 2006 in Santa Domingo and the following year in Chiang Mai in Thailand.

The 34-year-old, European champion in 2006, has been given a provisional suspension from the sport, the IWF has confirmed.

“The IWF reports that sample of Mr. Andrei Rybakov (BLR) has returned an Adverse Analytical Finding for (S4.5.3 Hormone and metabolic modulators) meldonium,” a statement from weightlifting’s worldwide governing body read.

“As a consequence, the athlete is provisionally suspended in view of a potential anti-doping rule violation.

“In any case where it is determined that the athlete did not commit an anti-doping rule violation, the relevant decision will also be published.”

The news comes after the IWF held an anti-doping seminar in Kazan, entitled “Enough is Enough”, in order to spread information on drug issues to athletes and their entourages.
