Russian Sports Minister Vitaly Mutko said on Friday that a total of 27 Russian sportsmen had already tested positive for the banned substance meldonium, R-Sport news agency reported.
A total of around 127 sportsmen have tested positive for meldonium globally, he said.
"Twenty-seven have tested positive for meldonium and there are some 127 cases in the world," Mutko told R-Sport news agency. "But these figures can change."
He said the punishment handed out by the Court of Arbitration for Sport (CAS) to a group of Russian speed walkers was not "completely right".
