Marouane Fellaini and Robert Huth have both been charged for alleged acts of violent conduct which were not seen by the match officials but caught on video.
The Manchester United midfielder and Leicester City defender were involved in an incident in the 21st minute of their game on Sunday [1 May 2016].
Both players have until 6pm on Wednesday 4 May 2016 to reply to their charge.
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.
