Chelsea have accepted the Football Association's fine of £20,000 after failing to control their players during the 1-1 draw with Huddersfield Town on May 9.
Antonio Rudiger, Cesar Azpilicueta and Cesc Fabregas led the protests after referee Lee Mason blew the half-time whistle just as Willian was preparing to take a corner.
A FA statement on Wednesday read: "Chelsea have been fined £20,000 after accepting a charge for failing to ensure their players and/or officials conducted themselves in an orderly fashion.
"The incident occurred at half-time during the game against Huddersfield Town on Wednesday, May 9."
