Southampton have been fined 20,000 pounds for failing to control their players during Saturday's goalless draw with Norwich.
Saints players surrounded referee Mark Clattenburg after he awarded a penalty for a foul by Luke Shaw on Grant Holt in injury time.
Artur Boruc saved Holt's subsequent penalty, and the game ended level.
The Football Association on Friday confirmed Southampton admitted a charge of failing to control their players, and had issued the fine as a result.
Southampton have won just one of the seven matches they have played under new boss Mauricio Pochettino, and sit 16th in the Premier League table.
