Are you sure of that, because most fixtures could have been played this weekend by clubs unaffected by the virus. National League games are still going ahead after all.
Arsenal and Chelsea off due to isolation. Mendy at Man City. 3 Leicester players. Who did they all play last weekend that they have been in contact with that need testing and might test positive? With positive cases isolating for 14 days and anyone in close contact self isolating it would quickly mean that no fixtures could be fulfilled.
