I think they are better off being cautious with them. Tiredness and reduced lung capacity can hang around for a few weeks. Push them too hard and they might not get back to 100% for awhile.If they've just had COVID (and they'd be playing if they didnt), there's almost no chance they get it again this weekend.
I'd hope they play even if only 1/2 a game, especially against the WC team
I got covid recently and I don’t think I am ever going to go for a run again.
