CAS general secretary Matthieu Reeb said that it was up to the IOC to decide on the participation of Russian athletes and suggesting it could be determined "even on a case-by-case principle".
"The IOC takes note of the announcement of the decision by the Court of Arbitration for Sport. We will now have to study and analyze the full decision. The IOC decision on the participation of the Russian athletes will be taken in the coming days," the press office said in a statement.
In the meantime, the Russian Olympic Committee canceled a ceremonial send-off of the national team to the Rio Olympics scheduled for July 22 after a sports court rejected ROC’s appeal against an athletics ban, head of the Russian delegation Igor Kazikov told R-Sport on Thursday.
