The Court of Arbitration for Sport (CAS) will hear biathlete Evgeny Ustyugov’s appeal against his doping ban on October 20.
The case was included in the latest list of hearing dates announced by CAS.
Ustyugov was sanctioned in March by the International Biathlon Union's (IBU) Anti-Doping Hearing Panel.
He was found to have been in breach of regulations based on analysis of the Moscow Laboratory Information Management System database.
An IBU statement said Ustyugov had "committed an Article 2.2 ADRV [anti-doping rule violation] under the 2012 IBU Anti-Doping Rules" by using the prohibited substance oxandrolone.
Ustyugov's results from August 27 2013 through to the end of the 2013-2014 World Cup season are set be disqualified.
This would see Russian stripped of his team relay gold at the Sochi 2014 Winter Olympics, which would also lead to team mates Anton Shipulin, Dmitry Malyshko and Alexei Volkov losing their medals.
Ustyugov was also handed a two-year ban, despite having already retired.
Ustyugov announced in March that he would be appealing the decision to CAS.
The hearing is confirmed for October 20.
It was reported by Russian state news agency TASS that Ustyugov has undergone genetic tests to prove his innocence.
Ustyugov has also reportedly filed a lawsuit against the IBU in the Austrian state court after he was charged in a separate case by the Biathlon Integrity Unit (BIU).
The BIU charged Ustyugov because of abnormalities in his Athlete Biological Passport in the period between January 2010 and February 2014.
Ustyugov is a double Olympic gold medallist, having won the mass start at Vancouver 2010 and also picked up a bronze in the relay at those Games.
