Motherwell manager Stephen Robinson is another who is unhappy at having to do without two first-choice midfielders because of the Scotland Under-21 Covid-19 outbreak.

"I got told at 11 o'clock today that Allan Campbell and Barry Maguire have to self-isolate," he tells BBC Scotland. "I got first wind of it when I got a phone call at quarter past 10 last night and informed that there might be a problem, but that's not good enough.

"I know that the boys were tested when they first met up. Obviously, I would hope that, after the staff member tested positive, all the players would be tested again - that's certainly what we do at our football club. If it wasn't then why not?

"I am a big supporters of the Scotland national team, but now it is coming back to affect clubs. I have lots of questions that I would like to ask about it."

Seventh-top Motherwell head to Perth, ahead of their hosts on goal difference but face a side who are developing McDiarmid Park as a bit of a fortress.

St Johnstone haven't lost a goal in their last four home matches, the last to score at McDiarmid Park being reigning champions Celtic in a 2-0 win at the start of October.

Indeed, Callum Davidson's side have suffered just one defeat in seven, and even that was on penalties after a 0-0 draw with Dundee United in the League Cup.

Motherwell suffered a 4-1 home defeat by Celtic last time out but have won their last two Premiership games on the road, scoring five goals without conceding.

"We do ask questions of the SFA. We had the whole Ryan Christie issue the last time and now we have another player affected. It's not good enough, it's a shambles.

"We haven't had any positive tests within our bubble, they've all been when players go on international duty. We were ravaged the last time."

Livingston will be without goalkeeper Robby McCrorie, who has tested positive for Covid-19 following Scotland Under-21 duty, and manager Gary Holt has been telling BBC Sportsound: "He [McCrorie] got tested first thing Thursday or Friday morning when he came in and it came back positive. He's isolating now and the protocols we have in pace have caught it.

On the financial impact of Covid-19: "I've been crying out from day one that we need help. Every sport in Scotland needs help. Lyndon’s [Dykes] sale has helped the club. Everything helps but we need help for the government. We have seen a package released down south, are we going to get something up here as well?

On the challenge facing them today: "St Mirren play nice football, they’ve got threats, but we know what we need to do. We need to make in uncomfortable as possible for them. We've went away from that a wee bit, so we want to be at it today and put a marker down."

With Motherwell shorn of the services of Scotland Under-21 midfielders Allan Campbell and Barry Maguire because of Covid-19 protocols, it has forced manager Stephen Robinson into two changes from the 4-1 defeat by Celtic a couple of weeks ago.

One game has bitten the dust today in League Two, with Albion Rovers' game away to Cowdenbeath being postponed because the visitors suffered a Covid-19 outbreak.

It means Brechin City have the chance to move above Rovers at the foot of the table should they draw today, but they have their work cut out as they visit unbeaten leaders Queen's Park.
