If many more games get canned it's going to make this season a bit of a farce and with the new Covid strain apparently being substantially more contagious that seems a distinct possibility. There is also the strong possibility of another national lockdown with all sport stopped as Heathen mentioned. If that happens I can't see how there can possibly be promotion and relegation this season, there may not be a game played in the Championship for starters.
Of course if there's no promotion the EA's will start screaming about a conspiracy to keep them out of the Premiership. Poor loves....
