Dundee United midfielder Calum Butcher could be handed a retrospective red card for his horror challenge against Celtic.
The 30-year-old came off the bench on Sunday at Tannadice, making his return from a two-match ban, and was booked for a high tackle on David Turnbull.
The challenge was slammed by pundits, with Neil McCann calling it a "leg-breaker" and Kris Boyd stating Turnbull was lucky not to be seriously hurt.
Referee Don Robertson did book the United man which would usually mean that no further action can be taken.
However, it's understood the incident is being reviewed, with Robertson to learn by 2pm on Tuesday if he'll face an SFA rap.
The rules do allow for retrospective action in cases where a potential red card has been missed by the match officials.
Disciplinary rule 200 states: "Where it is established that a player has committed any one or more of the following sending off offences during a match:(A1) Serious foul play (as described from time to time in the Laws of the Game), but only where the acts and/or omissions constituting the sending off offence: (i) were committed intentionally; and/or (ii) fell significantly below thestandard of conduct expected of a player in the prevailing circumstances; and (iii) in the case of each of (i) and/or (ii) above, demonstrate a culpable disregard by the player for the consequences which might result from such acts and/or omissions.
"Violent conduct (as described from time to time in the Laws of the Game), biting or spitting at someone, and, in the case of each or any of A1, A2 and/or A3, where the player was not dismissed by the referee as a result of the alleged act/acts referred to within the Fast Track Notice of Complaint.
"Any Fast Track Notice of Complaint alleging a breach of this rule shall be determined by a Fast Track Tribunal subject to the provisions of Section 13."
