Police Scotland are making enquiries into an alleged racist incident involving Celtic's Aleksandar Tonev and Shay Logan of Aberdeen.
The Scottish Football Association has now received an official complaint about the alleged incident and it will decide over the next few days if there are grounds to take disciplinary action against Tonev, who denies the accusation.
SFA president Campbell Ogilvie said: "The SFA have received a complaint and it is now in the hands of our compliance officer and it will go through the process. The compliance officer will have to take care of it.
"I can't comment on the case but it is it not something that comes up very often, obviously."
Dons defender Logan reported the alleged second-half incident immediately to referee Bobby Madden and skipper Mark Reynolds before informing manager Derek McInnes.
Fourth official Crawford Allan and Celtic were also made aware of the allegation by the Dons management team.
Bulgaria winger Tonev, 24, was making his belated Celtic debut after arriving in the summer on a one-year loan deal from Aston Villa with a groin injury.
Ronny Deila's side won the match at Parkhead 2-1 thanks to goals in either half from Jason Denayer and Kris Commons, to end a run of four games without a victory.
