Aleksandar Mitrovic is facing a three game ban after being charged by the Football Association.
The Newcastle striker has been charged with an alleged act of violent conduct from Saturday's win over West Ham.
Mitrovic appeared to clash with Manuel Lanzini in an incident that was not seen by any of the match officials at St James' Park.
The Serbian was a second half substitute and went on to score the third and final goal in the 3-0 win.
An FA statement said: "Aleksandar Mitrovic has been charged for an alleged act of violent conduct which was not seen by the match officials but caught on video.
"The Newcastle United forward was involved in an incident with West Ham United’s Manuel Lanzini in the 80th minute of the game on Saturday (26 August 2017).
"He has until 6pm on 30 August 2017 to respond to the charge."
FA chiefs are able to retrospectively ban footballers for incidents that are not included in a referee's post-match report.
The statement continued: "Off the ball incidents which are not seen at the time by the match officials are referred to a panel of three former elite referees.
"Each referee panel member will review the video footage independently of one another to determine whether they consider it a sending-off offence.
"For retrospective action to be taken, and an FA charge to follow, the decision of the panel must be unanimous."
