Moscow: The Meldonium concentration in the blood sample of Russian tennis star Maria Sharapova exceeds the permissible level, Russian Sports Minister Vitaly Mutko has said.

"Masha’s case is more complicated. The Meldonium concentration in her blood is above the norm. Masha took the formula for several year on her doctor’s prescription. I am not going to announce if she will be able to avoid punishment or not. We just want her to restore her position in sport," Mutko stressed, in an interview aired by Match TV on Wednesday, reports Tass.
