More than two dozen Russian athletes had their Olympic doping bans overturned after their appeals were upheld by sport's highest tribunal, but it remains unclear whether or not they will be able to compete in the upcoming Winter Games in South Korea.
In a decision issued on Thursday, the Court for Arbitration for Sport (CAS) said it "unanimously found" that the evidence presented against 28 athletes were "found to be insufficient to establish" that doping rules were violated.
