The Scottish Football Association have confirmed they are investigating Allan McGregor's alleged kick out at Aberdeen's Chris Maguire.
Rangers keeper McGregor has been referred to Hampden's disciplinary committee following an incident in the 3-2 win at Pittodrie played nearly two weeks ago.
The timing of the investigation is even more puzzling as McGregor is currently preparing for Scotland's crunch Euro 2012 qualifier against Czech Republic in Prague.
The 28-year-old, currently away on international duty, could receive a one-match ban for the incident, which took place at Pittodrie last month.
An SFA spokesman stated on Friday: "We can confirm an investigation has been initiated into an incident not witnessed by the match official."
A disciplinary panel will discuss the matter in Glasgow on Friday.
