lets hope that this restriction wont last more than a ~month
I don't think so.
In my local, the most popular cricket league IPL has been postponed and the governing body is yet to come to a fix date. There's no certain time frame when it may start although some say it will be around last of April but the way Covid19 is spreading I doubt it will be easy to start within 1 month. I guess it will exist much longer than we are expecting it to be.
Its indefinite. therefore, we should really expect that this would really extend if we cant see any signs of slowing down of progress of corona virus.
As long it wont get resolved then its expected that this would extend out and this wont only affect sports industry but others as well.
Lets hope that this wont get worst even more.
There are no more Horseracing in the UK until the end of April

, the Grand National is postponed

Irish Horseracing and all Greyhound racing is moving behind closed doors, but until when? We can see a shutdown of all races soon, it depends on the government decision, and lets hope that this restriction wont last more than a ~month
in italy too same situation.
A very interesting thing in Italy is that related to football. friendly matches in
esports have been set up, and people like it.
they are now thinking of making official matches, a sort of virtual championship (esport)
It would be somewhat understandable if esports would become virtual or would proceed or doesnt totally postponed yet
their matches can be done via pc so its understandable that they can still proceed in spite of this current problem
but well there would be not audience.
