Celtic forward Ryan Christie has been hit with a notice of complaint by the Scottish Football Association for an alleged incident involving Alfredo Morelos in the 2-1 defeat to Rangers on Sunday.
Christie had already been booked when he was penalised for fouling Morelos on the hour mark in the Old Firm clash at Parkhead, with replays appearing to show an alleged grab at the Colombian's groin area.
Referee Kevin Clancy did not show the Scotland international a yellow card for the incident.
The complaint is raised under rule 200, A2. The hearing will take place on January 6 and if found guilty, the sanction would carry a two-match ban.
Christie saw a first-half penalty saved by Rangers goalkeeper Allan McGregor at Parkhead, with the visitors claiming a win which moved them to within two points of Premiership leaders Celtic with a game in hand going into the winter break.
