MOSCOW, May 15. /TASS/. A bout between Russian heavyweight Alexander Povetkin and American Deontay Wilder for the world title in the super heavy category according to the World Boxing Council (WBC) has been postponed, Andrei Ryabinsky, the head of the Mir Boksa (Boxing World) promotion company, which represents Povetkin’s interests, said on Sunday.
"Povetkin’s bout vs Wilder has been postponed. It will take place on another day," he wrote on his Twitter account.
Low concentrations of meldonium (0.07 microgram) have been found in Povetkin’s blood sample ahead of the bout vs Wilder. Povetkin reportedly last used the formula in September 2015. It became known later that his three previous samples taken on April 7,8 and 11 were meldonium negative. The positive sample was taken on April 27.
"We invite journalists to a news conference at the Renaissance Moscow Monarch Centre Hotel tomorrow at noon. We will provide all the details, about meldonium including," Ryabinsky wrote.
The bout was to take place at Moscow’s Megasport complex on May 21.
The drug meldonium (mildronate) was included in the list of preparations banned by WADA from January 1, 2016. The presence of the meldonium substance in the athlete’s blood during and between competitions is a violation of anti-doping rules. The substance belongs to S4 class on the WADA blacklist (hormones and metabolic modulators).
On April 13, WADA announced that the concentration of less than one microgram of meldonium in the body system of an athlete, whose doping tests were conducted before March 1, was acceptable.
Meldronate is a cardiovascular preparation freely available for purchase at pharmacies across Russia without doctor’s prescription.
Almost 300 athletes have tested positive for meldonium, according to WADA. According to TASS sources, at least 31 Russian athletes are suspected of using the prohibited medical formula.
Athletes use meldonium (mildronat) for enhancing endurance to high physical exertion during training sessions and emotional stresses during competitions. In some CIS countries, meldonium is used a medicine against heart diseases.
