Celtic could reportedly face SPFL sanctions for Boli Bolingoli's coronavirus breach.
The joint reponse group outlined new measures after the left back failed to quarantine on his return from Spain, and the eight Aberdeen players who visited a pub on the opening weekend of the Premiership season.
Under the new guidelines, it is suggested those players will be disciplined by the SFA for breaking quarantine rules.
But STV are reporting Celtic and Aberdeen could also be punished by the SPFL for their players not adhering to the regulations.
They would attend a SPFL hearing to make their case, before their fate would be decided.

It is expected league chiefs will release more details about the new coronavirus disciplinary procedured on Friday.
Hearts have also been ordered to stop training despite Robbie Neilson's men returning to Riccarton last week.
Training for clubs outwith the Premiership is now delayed until August 24 as they try to implement the new changes before the lower leagues start in October.
