International Tennis Federation (ITF) president David Haggerty says a disciplinary hearing has been scheduled in Maria Sharapova's doping case, with a ruling possible before Wimbledon.
Haggerty has told reporters the independent Tennis Integrity Unit typically takes "two to three months" to process a case. That could deliver a verdict in June.
Haggerty said he had not been told details of the case, including when and where the hearing would be held.
Sharapova was provisionally suspended after announcing on March 8 that she had tested positive for meldonium in January at the Australian Open.
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 January 1.
