MARIA SHARAPOVA was today ruled out of the Olympics and the US Open after the Court of Arbitration for Sport announced it would not rule on her drugs ban until September.

The 2004 Wimbledon champion was banned for two years by the ITF after testing positive for meldonium in January.

Sharapova immediately appealed to CAS, hoping for a hearing before the July 18 cut-off point for teams to be finalised for Rio 2016.

Sharapova admitted she had been using the heart drug for 10 years and felt the ITF had not done enough to alert players to the fact it had been added to the World Anti-Doping Agency's banned list on January 1 this year.

Sharapova is the most high-profile cases that hit anti-doping authorities in 2016: as of mid-April, WADA was aware of 172 positives for the drug since the start of the year.
