CAS said that its secretary general Matthieu Reeb would make a statement at 1700 local time (0800 GMT) in Pyeongchang, South Korea, where the tribunal has set up a temporary office for next month's Winter Olympics. The decisions will also be issued on its website, CAS said.
The athletes were disqualified from their events, banned from participating in future Olympics and in some cases stripped of their medals following the International Olympic Committee’s investigation of widespread doping in Sochi.
Russia has repeatedly denied any state involvement in the doping which was exposed by an independent report commissioned by the World Anti-Doping Agency (WADA).
