Maria Sharapova has appealed to the Court of Arbitration for Sport (Cas) after being banned from tennis for two years for using a prohibited drug.
Sharapova, who tested positive for meldonium at January's Australian Open, was last week suspended by the International Tennis Federation (ITF).
The 29-year-old, a five-time Grand Slam winner, said in her appeal her ban should be "eliminated" or reduced.
Cas said it would rule on the Russian's case by 18 July.
A statement from Sharapova's lawyer said the ITF's tribunal reflected the player "did not intend to violate the rules".
