Javier Mascherano has been charged with improper conduct by the Football Association.
The Liverpool midfielder faces further disciplinary action following his reaction to being sent off by referee Steve Bennett in the defeat by Manchester United at Old Trafford on Sunday.
Mascherano had to be held back by his team-mates, manager Rafa Benitez and members of the Liverpool back-room staff after being shown a second yellow card for questioning Bennett’s decision to book team-mate Fernando Torres.
A statement from the FA read: “The charge relates to his reaction towards referee Steve Bennett after being sent off against Manchester United on Sunday, 23rd March.
“He has until 6pm tomorrow to respond. The case will be heard by a regulatory commission on Friday, 4th April.
“Mascherano is currently serving a one-match suspension for the sending-off.”
