The reverberations from an epic Sydney derby continue to be felt with the Sky Blues' towering defender Sasa Ognenovski facing a possible ban after he lashed out during a heated battle.
In a melee sparked by an ugly challenge on Sydney’s Terry Antonis, Ognenovski - who was already on a yellow - appeared to slap the back of the head of red-carded Vitor Saba.
Ognenovski has been cited for his part in the ensuing flashpoint and a show cause notice has been issued by the independent Match Review Panel.
The ex-Socceroo and former Asian Player of the Year has until midday Tuesday to respond to the notice, after which the MRP will reconvene to consider any submissions from the player or club.
In considering Saba’s infringement, the MRP decided the minimum one match ban was sufficient sanction for the flying studs up challenge on Antonis.
Ognenovski was fired up for the crosstown clash, pushing away his own goalkeeper Vedran Janjetovic for assisting Wanderers' Brendan Hamill after he went down with cramp.
Football Federation Australia is also expected to investigate the use of flares at the game and a pitch invasion by fans following Sydney skipper Alex Brosque’s match winner.
Sydney came from two goals down to seize the derby 3-2 on Saturday.
