Emirates club did not control players at St James’ Park.
Arsenal and Newcastle United have both been fined £30,000 for failing to control their players during the bad-tempered goalless draw at St James’ Park on August 13.
Gunners forward Gervinho was shown a red card for striking Magpies midfielder Joey Barton after the pair had squared up in the second half.
Alex Song was also handed a three-match ban for stamping on Barton, an incident which was not seen by referee Peter Walton.
The Football Association have now announced more bad news for the north Londoners because of the melee which followed Gervinho’s sending off.
“An independent regulatory commission today found both Newcastle United and Arsenal guilty of failing to control their players,” an FA statement read.
“The charges relate to an incident during their recent league fixture at St James’ Park on Saturday 13 August 2011.
“Both clubs denied the charge and requested a non-personal hearing.
“In each case, the charge was proven by the regulatory commission and both clubs have been fined £30,000.”
Newcastle have asked for details behind the decision before considering their position.
“Newcastle United has requested written reasons for the decision from the chairman of the regulatory commission and will consider its position once these have been received,” a Magpies statement read.
