International Tennis Federation president David Haggerty says a disciplinary hearing has been scheduled in Maria Sharapova's doping case, with a ruling possible before Wimbledon.

Haggerty tells reporters the independent Tennis Integrity Unit typically takes "two to three months" to process a case. That could deliver a verdict in June.

Haggerty says he has not been told details of the case, including when and where the hearing will be held.

Sharapova was provisionally suspended after announcing on March 8 that she tested positive for meldonium at the Australian Open in January.

The Russian said she had been prescribed the blood-flow boosting drug since 2006, and had been unaware the World Anti-Doping Agency had prohibited its use from Jan. 1.

Russian officials want Sharapova to play at the Rio de Janeiro Olympics in August.
