Nigel Pearson has been handed a £5,000 fine by the FA following comments made against referee Andy Davies last month.
The Bristol City manager, who avoided a touchline ban, was heavily critical of the official after watching his side fall to a last-gasp 2-1 defeat at home to QPR.
He claimed Alex Scott was denied a clear first-half penalty and also bemoaned the decision to award QPR a corner that led to the Hoops' winner in injury time.
