Celtic and Boli Bolingoli are set to be punished by league chiefs after the left back's coronavirus breach.
The SPFL and SFA outlined new measures on Thursday after the left back failed to quarantine on his return from Spain.
Eight Aberdeen players, who have been heavily fined by the club, were also forced to isolate after visiting a pub on the opening weekend of the Premiership season, as two tested positive for Covid-19.
The new disclipinary measures were yet to be confirmed, but the joint reponse group has now released their new procedures, with players and clubs both facing sanctions.
The SFA will now look into the 'Aberdeen 8' and Bolingoli following their actions. A hearing date has been set for August 28.
