Manchester United have been charged with "failing to control their players" by the Football Association following Monday's FA Cup quarter-final tie.
The charge relates to an incident in the 35th minute following the dismissal of United midfielder Ander Herrera by referee Michael Oliver.
Herrera picked up two cautions - both for fouls on Eden Hazard - and was sent from the field with United players crowding around Oliver as they vehemently protested against the second booking.
Chelsea went on to win the match 1-0 thanks to N'Golo Kante's goal early in the second half to set up a semi-final with Tottenham.
United have until 18:00 GMT on Friday to respond to the charge.
