Delay in ruling keeps banned Sharapova on sidelines

The Court of Arbitration for Sport said on Monday it has delayed ruling on the two-year doping ban for Maria Sharapova until September, keeping the tennis superstar out of the Rio Olympics.

The 29-year-old Russian tested positive for the banned medication meldonium during January's Australian Open.

If the ban - which Sharapova has called "unfairly harsh" - is upheld it would almost certainly end one of the sport's most celebrated and high-profile careers.
