Manchester United's Marouane Fellaini and Leicester City's Robert Huth have been charged with violent conduct by the Football Association.
The charges relate to an incident during Sunday's 1-1 draw at Old Trafford, which was not seen by the match officials but caught on video.
Huth appeared to pull the hair of Manchester United's Fellaini as a corner was played in, before the latter twice aimed an elbow towards the Leicester defender.
The players have until 6pm on Wednesday to reply to the 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.
After Sunday's match, Manchester United manager Louis van Gaal defended Fellaini's actions, saying they were a response to having his hair pulled by Huth in the first instance.
"When you look at what Huth is doing with Fellaini, that's a penalty," he said. "Shall I grab your hair? What is your reaction, when I grab your hair? Your hair is much shorter than Fellaini, but when I do that, what are you doing then?
"I think that's a normal reaction. You have to first pick Huth, because he was the guy who grabbed the hair of Fellaini. I think the reaction of Fellaini is like a human being."
