The usually mild-mannered Spaniard and former Barcelona great was visibly aggrieved when Glory were awarded a goal which saw goalkeeper Eugene Galekovic knocked to the ground in the build-up.

As well as taking part in a verbal joust it is understood the 48-year-old grabbed the fourth official.

The matter of “unsporting conduct towards a match official” was referred to the Disciplinary and Ethics Committee by the Match Review Panel.

It means Amor will be forced to watch from the stands at Allianz Stadium as the rock-bottom Reds take on league leaders Sydney FC on Saturday.

Speaking to Fox Sports News after the event, former Reds coach said it was unusual for Amor to get angry, descrbing him as the "epitome of peace and tranquillity".

Football Federation Australia released a statement saying: “The Match Review Panel (MRP) regarded the incident constituting unsporting conduct towards a match official and has referred the incident to the Disciplinary and Ethics Committee for hearing regarding what sanction should apply over and above the Mandatory Match Suspension (which Amor must serve against Sydney FC on Saturday, 26 November 2016),” a statement read.

“The Disciplinary and Ethics Committee hearing date is to be confirmed.”

Adelaide have yet to win a match this season, and have picked up just a couple of draws to be sitting on two points after seven rounds.

Kosmina told Fox Sports News: "For Gui Amor to get upset where he does get sent off…here’s the guy who’s been the epitome of peace and tranquillity on the sideline. He never ever gets angry.

"Apparently with the players at half-time, before and after the game, never ever raises his voice – everything is always calm and measured."

Kosmina said Amor may have touched the official to get his attention.

"(Amor) obviously upset with the decision…I did get the impression looking at the visionas he was being sent off that he was waving his finger towards the fourth official and almost saying, 'no you don’t do that'.

"Now maybe the fourth official put his finger into Amor’s face and I don’t agree with that either.”

Kosmina added that officials waving a finger or putting a hand up to the face of a player or coach was “very inflammatory".
