The Court of Arbitration for Sport has confirmed that the decision regarding Maria Sharapova's appeal against a two-year ban will be announced on Tuesday.
The five-time Grand Slam winner, 29, was banned by the International Tennis Federation after testing positive for meldonium - banned since January 1, 2016 - at this year's Australian Open.
Sharapova, who said she had been taking the drug since 2006 for health problems, appealed against the ban, maintaining that she had "not tried to use a performance-enhancing substance".
In a statement released on Monday, CAS said that its decision would be announced at 2pm BST the following day.
Sharapova's last official match was her quarter-final defeat to Serena Williams at the Australian Open in January.
