In Australia we're just on round two of the NRL season and all games have to be played behind closed doors (televised though). Their theory is to ensure that no-one in the team of staff has the virus and to basically self-isolate them all. There was even talk of basing ALL 16 teams in one venue and playing all games there. The CEO of the NRL has said that if games aren't played, due to sponsorship deals etc, then the game won't survive financially in Australia.
The World is a very different place than it was a month ago....
