London - West Ham were fined £30 000 by the Football Association on Friday for failing to control their players in the goalless draw at Southampton earlier this month.
The incident occurred after referee Craig Pawson sent off West Ham goalkeeper Adrian just after the hour for handling the ball outside his penalty area.
Although Adrian's red card at St Mary's was overturned on appeal, the FA announced the Premier League club have been punished for their players' angry reaction to the Spaniard's dismissal.
"Following an independent regulatory commission hearing, West Ham United have been fined £30 000 after the club admitted an FA charge of failing to ensure its players conducted themselves in an orderly fashion," a statement on the FA's official website read.
"The charge was in relation to an incident which occurred in or around the 61st minute of the game against Southampton on 11 February 2015."
