Can't see them doing that will call off all games.
Toronto have been in contact with Leeds and Huddersfield players in the past 10 days.

And Huddersfields games as the Wolfpack have just played them don't forget, indeed at least the last couple of weeks teams will have to be tested surely?

Only if they start showing symptoms. I honestly think that’s how they’ll deal with it.

At all costs they’ll try to keep the games going ahead and I understand why.

Obviously could be wrong, just get the impression they’ll deal with each case seperately unless players from several clubs are all confirmed to have the virus.

...or they've got a cold.

Why would RL be just about the only sport to keep going

Because they are following the Government guidelines.

Or maybe not enough fit players.

or it really suits them if the season is cancelled, therefore no chance of relegation

Or they are taking a global pandemic seriously

They're living in England, it didn't stop Cas and Saints yesterday or the cup games going ahead.

The 4 Toronto players that isolated themselves live in England?

Apologies, should have put staying in England.

Although it will be immaterial if they suspend SL and the Championship, I wonder what the protocol is for clubs that have players suspected of having the virus and if the comp was to continue, how long said clubs could / should postpone fixtures or, how many players suspected of having the infection allow a club to cancel / postpone fixtures. The answer to this may be just 1, as Leeds refused to travel to Perpignan for their game.
There will be much wider issues with Catalan, with much of France now in lockdown, I cant see them either wanting to or being able to travel in and out of France to play Rugby League.

Remi Casty has already said he isn't going anywhere, and I cant say I blame him.

In anything like "normal" circumstances that would be for the club to deal with.
As we are, I think that the RFL & SL will need to issue some guidelines and directives for clubs and players alike.

I wonder how many Rhinos fans travelled over to Perpignan for their postponed game and whether they all made it back home.

There are huge problems in France and Spain, as there will likely be over here.

However, I dont think its for Remy Casty or any other player to dictate the tone or decide the way forward for the game, this has to come from those running the sport.
