Leicester City have been charged by the Football Association for failing to control their players in last Saturday's 4-1 win over Huddersfield.
City players surrounded referee David Coote to protest the penalty he awarded to the Terriers for a foul by centre-back Caglar Soyuncu on Karlan Grant.
They have until Friday to appeal the charge.
In a statement, the FA said: "Leicester City FC has been charged with a breach of FA Rule E20 following the Premier League game against Huddersfield Town on Saturday.
"It is alleged the club failed to ensure its players conducted themselves in an orderly fashion during the 51st minute.
"The club has until Friday (April 12) to respond."
Like his players, City manager Brendan Rodgers did not believe the decision was a correct one.
He said after the match: "It wasn't a penalty. Cags has got a good touch on the ball."
If the charge is upheld, City will likely have to pay a fine.
