The career of Russian former world number one Maria Sharapova was in tatters on Wednesday after she was given a two-year ban by the International Tennis Federation (ITF) following her positive test for the banned drug meldonium at this year's Australian Open.
In a statement the ITF said the 29-year-old five-times grand slam champion's ban would be backdated to Jan. 26 this year, meaning her results and prize money from the Australian Open, where she reached the quarter-finals, would be cancelled out.
Sharapova said she would appeal to the Court of Arbitration for Sport (CAS), describing the punishment as "unfairly harsh".
She said an independent tribunal in London on May 18-19 had found that she had not intentionally violated anti-doping rules.
