Belarusian silver and bronze medalists in the men's Olympic hammer throw competition have tested positive for doping and been provisionally suspended, the IAAF said on Friday.

Vadim Devyatovskiy and Ivan Tsikhan, who finished second and third at last month's Olympics in Beijing, are still being investigated by the International Olympic Committee and risk being stripped of their medals.

"For the IAAF it is clear. It will be a suspension," IAAF president Lamine Diack said at the end of the Golden League meet in Brussels. "Now it goes to the level of the IOC but for us, it is clear."

The IOC said a disciplinary commission will meet at the end of the month to hear the case. The Belarus Athletics Federation said both Devyatovskiy and Tsikhan had denied the accusations.

If found guilty of doping offense, Devyatovskiy's silver would go to Krisztian Pars of Hungary, while Tsikhan's bronze would go to Koji Murofushi of Japan. Primoz Kozmus of Slovenia won the gold medal.
