St Mirren’s Scottish Premiership match against Motherwell has been postponed after another player at the Paisley club tested positive for Covid-19.
St Mirren say “a number of additional players” are now required to self-isolate, having already returned two positive tests on Thursday.
As a result they informed the SPFL they could not fulfil Saturday’s fixture.
“It is very disappointing that we are faced with this situation,” said chief executive Tony Fitzpatrick.
“Despite the numerous precautions and safeguards that are in place within the Club.
“This is hugely frustrating for our fans, the players and staff, and for everyone connected with the club.”
Motherwell’s last league fixture with Kilmarnock was also postponed when the Ayrshire club’s entire first-team was forced to self-isolate after six positive tests.
The SPFL say the game has been postponed pending an investigation, which was also the case for the outbreak at Kilmarnock.
The league added St Mirren informed the league they only had 12 registered players available, including four goalkeepers.
Uefa guidance, which has been adopted by the SPFL, says a fixture can go ahead as long as a team has 13 available players, including at least one goalkeeper.
“This once again underlines the absolute necessity of maintaining vigilance to ensure that players, officials and their families minimise the risk of infection to keep everyone safe,” Fitzpatrick added.
