Of the top 6ish teams - Stepanova/Bukin and Shevchenko/Eremenko have offically withdrawn as both teams have/had COVID in the last couple of weeks (the entire Zhuk/Svinin team had the virus it was revealed yesterday).Which is a shame. Have any of the listed teams actually withdrawn? I don't have the chance to keep 'up to the moment' with developments these days.
S/K is currently an assumption (I think) due to her knee injury.
The Russian fed did say something yesterday about reconsidering the qualifications for Nationals though. (Who knows if Worlds will go ahead but with the vaccination news the last couple of weeks I can see the ISU considering a reschedule for later in the Spring if that was an option for them.)
