A confrontation blew up at the end of the goalless Premier League draw after Canaries midfielder Leroy Fer attempted to score from a throw-in when Cardiff had put the ball out for an injury - the effort was ruled out by the referee on the basis that he had not restarted play.
An FA statement said: "Norwich City have been fined the standard penalty of £20,000 after admitting a breach of FA Rule E20(a) in relation to their game against Cardiff City on 26 October 2013.
"The charge was that the club failed to ensure its players conducted themselves in an orderly fashion in or around the 94th minute of this fixture."
Cardiff were also charged with the same breach which they have admitted.
The club has, however, rejected the standard penalty and a hearing will now take place to determine their sanction.
Not sure i agree with this, Leroy Fer caused the problem by lacking sportsmanship, the others were scuffling because of that. Surely Leroy Fer should be charged for bringing the game into disrepute. This is 2 teams who come the end of the season a point, or 3 points could be very important to them so rightly so Cardiff players would be angry if Leroy had taken that away from them.- dannyjohnson
