Chelsea have been charged by the Football Association for failing to control the players during the 1-1 draw against Huddersfield on Wednesday.
Referee Lee Mason blew the half-time whistle before Chelsea could take a corner, prompting the players to surround him.
A statement from the FA said: “Chelsea have been charged with failing to ensure their players and/or officials conducted themselves in an orderly fashion.
“The incident occurred at half-time of yesterday’s game against Huddersfield Town. Chelsea have until 6pm on Tuesday [15 May 2018] to respond to the charge.”
