Manchester United's Marouane Fellaini and Leicester City's Robert huth have both been charged with violent conduct following an off-the-ball incident during Sunday's 1-1 draw at Old Trafford.
The pair were involved in a 21st minute altercation which was caught on video but missed by match officials.
The players have until 6pm on Wednesday to reply to their FA charge.
If there are found guilty they will receive a three-game ban ruling each of them out for the remainder for the season.
"Each referee panel member will review the video footage independently of one another to determine whether they consider it a sending-off offence" the FA said in a statement today.
"For retrospective action to be taken, and an FA charge to follow, the decision of the panel must be unanimous."
Fellaini appeared to elbow Huth after the Leicester defender allegedly pulled his hair.
