A "furious" Nicola Sturgeon warned Scottish football that its permission to play would be risked if there was a repeat of the situation that saw two Aberdeen players catch Covid-19 following a trip to the pub.
Today's match between Aberdeen and St Johnstone has been postponed following Scottish Government intervention after eight Dons players were told to self-isolate on Thursday.
All eight visited a bar last Saturday in the city, which has been the subject of stricter local lockdown rules, and the decision was taken to postpone the Perth encounter following talks between Scottish sports minister Joe Fitzpatrick and the Scottish football authorities yesterday after cases in Aberdeen rose to 101.
"It is now clear that all eight of these players visited a bar in Aberdeen on Saturday night. In doing so they blatantly broke the rules that had been agreed between the SFA, the SPFL, and the Scottish Government, which, to put it mildly, is completely unacceptable.
"We are asking members of the public to behave in a highly precautionary manner and when a football club ends up with players infected with Covid - and let's remember this is not through bad luck but through clear breaches - we cannot take even a small risk that they then spread the infection to other parts of the country," said Sturgeon.
