LAUSANNE, Switzerland – The verdict in Maria Sharapova's appeal against a two-year doping ban will be announced Tuesday.
The Court of Arbitration for Sport says it will issue the decision at 3 p.m. local time (1300 GMT).
Sharapova challenged an International Tennis Federation ban imposed after she tested positive at the Australian Open for meldonium.
An ITF panel found that the Russian did not intend to cheat, but was at "very significant fault."
Sharapova acknowledged taking meldonium before each match in Melbourne, claiming she was not aware it had been banned by the World Anti-Doping Agency.
Sharapova said she was prescribed the Latvian-made heart drug since 2006. Meldonium, also known as mildronate, is not approved for use in the United States where she lives.
Her ban expires in January 2018.
