Two weightlifters were stripped off the competition result after their violation in the doping tests, the head of the International Weightlifting Federation (IWF) told the press on Friday.
The IWF president Tamas Ajan said on the press conference that Mukhit Usenbaev of Kazakhstan in men's 69kg class and Hnin Thant Zin of Myanmar in women's 53kg division had been disqualified in the ongoing world chamipionships, because they did not follow the procedure of the doping test.
"There is no positive result up till now in the doping tests, but these two lifters had manipulating behavior in the tests," Ajan said.
"We will give them a chance to defend themselves," he added.
A coach in Kazakhstan team told Xinhua that Usenbaev did not take the doping test because of not knowing there would be a test.
"He left the venue after he finished the competition," he said.
Neither Usenbaev nor Hnin has won a medal in the competition.
