Certainly in England I think the government are desperate not to prevent organised sports from carrying on, after all football is still fine even in cities and areas in tier 3. Problematic yes for leagues that span tier 3 and tier 1/2 areas as clubs from the former can't travel to the latter (but match officials can), but football is still being played. Of course a full lockdown is going to wipe out non-professional sport, but I think they would allow everything above National League to carry on unlike the last lock down.
Where I am a little baffled is how countries are saying they are doing a two to four week lock down to get control back, as after two to four weeks following the March full lockdown it took the best part of four months to lift those restrictions and I can't see why it would be any different now. I fear that if a full lock down is implemented that will be in place until at least March, they will just keep extending at the end of every period.
