A fine of £40,000 has also been imposed, suspended until June 30, 2021, pending any further breaches of the SPFL’s Covid-19 Regulations by the club.
An SPFL spokesman said: "The Covid-19 Regulations put in place by the SPFL and the detailed protocols issued by the SPFL/Scottish FA Joint Response Group are intended to enable Season 2020/21 to continue with the minimum of disruption and the minimum risk for those players and coaching staff involved."Strict adherence to these Regulations and protocols is therefore crucially important in order for Season 20/21 to be completed as scheduled."We note the admission by each of Kilmarnock and St Mirren that they breached SPFL Regulations and commend both clubs for the measures that their boards have.
