Former world number one Simona Halep's appeal against a four-year doping ban will be heard by the Court of Arbitration for Sport from Wednesday.
The Romanian, 32, was suspended after an independent tribunal determined she committed "intentional" anti-doping violations in September.
Halep, a two-time Grand Slam singles champion, said she would fight to clear her name of the "false allegations".
The hearing will take place over three days in Lausanne, Switzerland.
The Court of Arbitration for Sport (Cas) said on Tuesday: "The parties, witnesses and experts will attend the hearing both in person and remotely, including Ms Halep who will be present in person.
