Melbourne City's Tim Cahill has been handed a one-match suspension for his derby red card, while Dean Bouzanis faces a hearing on Wednesday for his "f***ing gypsy" slur against Besart Berisha.
The A-League's match review panel (MRP) revealed on Monday night that Cahill had committed the offence of "use of offensive, insulting or abusive language and/or gestures against a match official".
The 37-year-old was shown a red card, while waiting to come on as a substitute, following Melbourne Victory's controversial winning goal in Saturday night's derby at Etihad Stadium.
It is alleged Cahill called referee Chris Beath "a f***ing disgrace" after he chose to award Victory a goal in the 86th minute, with City defender Manny Muscat scoring into his own net as an offside Berisha stood behind him.
Cahill apologised to Beath on Monday night via his Facebook page.
"I sincerely apologise to Chris Beath for my reaction," he wrote.
"My behaviour also hurt the game so I also apologise to my team, to Melbourne Victory and to all the fans at the game and watching at home.
"Regardless of whatever happens on the pitch, I have to respect the game and the officials.
"I want the game to grow in Australia and I want to do all I can to help that happen.
"No matter the situation, I have to set an example and be accountable for my words and actions."
Meanwhile, Cahill's team-mate and City goalkeeper Bouzanis will learn his fate on Wednesday night when he faces Football Federation Australia's Disciplinary and Ethics Committee.
The MRP determined Bouzanis used "discriminatory language" towards Berisha when he called him a "f***ing gypsy" following Muscat's own goal.
Bouzanis has since apologised to the Victory striker.
With Cahill suspended and Bouzanis expected to be banned, City are likely to be without eight players for Saturday night's A-League fixture against Brisbane Roar.
Captain Bruno Fornaroli, Fernando Brandan, Osama Malik, Luke Brattan and Muscat all collected their fifth yellow cards of the campaign against Victory, which trigger one-match suspensions.
Meanwhile, defender Michael Jakobsen re-injured his calf against Victory - a fitness issue that cost the 31-year-old three matches in December.
