Wembley chiefs want answers from St James’ Park and Emirates clubs.
The Football Association have charged Newcastle United and Arsenal for failing to control their players during Saturday’s bad-tempered goalless draw at St James’ Park.
Gunners forward Gervinho was sent-off for slapping the Toon Army midfielder Joey Barton following an altercation between the pair.
Arsenal have appealed the red card, but midfielder Alex Song could now face disciplinary action after his stamp on Barton, which inflamed the situation.
This was missed by referee Peter Walton just like Barton’s grab on Gervinho, but the scouser will escape punishment as he received a yellow card for his part in the melee.
A statement from the FA read: “Newcastle United and Arsenal have been charged by The FA with failing to control their players following Saturday’s fixture at St James’ Park.
“Both clubs have been charged following a mass confrontation of players following an incident in which Arsenal’s Gervinho was also shown a red card in the 75th minute.
“Following Gervinho’s dismissal Arsenal have today lodged a claim that the standard punishment of a three-match suspension is clearly excessive.
“A Regulatory Commission will hear the claim on August 16.
“Meanwhile Arsenal’s Alex Song has been charged separately by The FA with violent conduct following an incident earlier in the same fixture.
“Both clubs have until 4pm on August 18 to respond to the charge, whilst Song must reply by 6pm on August 16.”
As it stands, Gervinho will serve an automatic three-match ban – missing games against Liverpool and Manchester United – with Song also being hit by the same retrospective punishment.
Barton, meanwhile, received a yellow card for his part in the melee, and as such has already been sanctioned.
He has admitted he “went down easily” following Gervinho’s slap, and also engaged in some heated exchanges on Twitter.
