Russia tennis chief still expects Maria Sharapova to play at Olympics

Russian tennis chief Shamil Tarpishchev expects Maria Sharapova to represent her country at this year's Olympics in Brazil despite being provisionally suspended from the game after testing positive for a banned substance. Five-times grand slam champion Sharapova said on Monday she had failed a drug test (see video below) at the Australian Open in January because of a substance, meldonium, she was taking for health issues.
