West Ham United have been fined £30,000 by the Football Association for failing to control their players against Southampton earlier this month.
The incident occurred when goalkeeper Adrian was sent off for appearing to handle outside of the penalty area during the goalless draw at St Mary's on February 11.
The governing body eventually rescinded Adrian's red card, but the club were charged following the reaction of the Hammers' players.
The club have admitted to "failing to ensure [their] players conducted themselves in an orderly fashion" during the Premier League match and have been fined as a result.
