Sharapova tested positive for drug, but will play at the Olympics

Sharapova, 28, tested positive for meldonium, a substance she has been taking since 2006 for health issues.
The International Tennis Federation (ITF) said the Russian five-time Grand Slam champion would be provisionally suspended from 12 March.
Sharapova could face up to a four-year ban.

But Russian Tennis Federation president Shamil Tarpishchev told the TASS news agency: "I think this is just a load of nonsense.

"The sportsmen take what they are given by the physiotherapists and by the doctors.
"I think Sharapova will play at the Olympics. However, we will need to see how this will develop."The Games in Rio de Janeiro start on 5 August.
She revealed she failed a drugs test at January's Australian Open at a news conference in Los Angeles on Monday.
"I did fail the test and take full responsibility for it," said the former world number one, who won Wimbledon as a 17-year-old in 2004.

Sportswear giant Nike has already suspended its contract with the player.
