IPC president Andrew Parsons says “much to our growing disappointment and frustration, there is a lack of progress” from Russian authorities on the IPC’s demand that they either accept or disprove evidence they ran a doping program.

The IPC says a final decision will be made “in late January.”

Russia was barred from the 2016 Paralympics in Rio de Janeiro because of doping.

Then-IPC president Philip Craven said at the time that the Russian government’s “medals over morals mentality disgusts me.”
