Birmingham City have been fined £10,000 after being found guilty of failing to control their players during last month's 1-0 derby defeat by Aston Villa.
The Football Association has handed down the financial punishment and also warned the Blues over their future conduct following the defeat at Villa Park.
Referee Martin Atkinson angered the City players after awarding a late penalty after Roger Johnson was adjudged to have fouled Gabriel Agbonlahor.
Johnson himself was fined £7,500 last week after his post-match criticism of Atkinson, who he labelled "a disgrace".
The 27-year-old was also warned about his future conduct after suggesting the game was "too big" for the official.
Following a disciplinary hearing on Thursday, the club have now been sanction.
An FA statement read:"At an Independent Regulatory Commission earlier today, Birmingham City were fined and warned as to their future conduct following a charge of failure to control their players.
"Having admitted the charge and taken into consideration the club's previous record, the commission ordered that they be fined £10,000."
