Livingston striker Dolly Menga has been offered a two-game ban after allegedly aiming a headbutt at Celtic forward Ryan Christie.
The Angolan was caught on camera motioning his head into the face of the Hoops ace during Sunday's 0-0 draw at the Tony Macaroni Arena.
The incident was missed by referee Keven Clancy but Menga has now been handed a fast track notice of complaint from Scottish Football Association compliance officer Clare Whyte.
If he accepts the violent conduct charge, he will miss Livi's next two games against Rangers and Motherwell.
A hearing has been set for Thursday.
Celtic boss Brendan Rodgers said after the game: "He should have been sent off. I thought so in real time.
"I thought he gestured his head towards Ryan and when I saw it after the game it was actually more aggressive than I thought and he was very, very lucky to stay on the pitch.
"If he goes down it doesn't matter if the referee hasn't seen it. I assume he hasn't seen it so if he goes down or not it doesn't matter.
"It wasn't a great action by the player so you can only assume all the officials haven't seen it."
