Brandao has been provisionally suspended until mid-September following his head-butt on Paris Saint-Germain's Thiago Motta.
Brandao, 34, attended the French Football League (LFP) disciplinary commission's preliminary hearing into the incident in Paris on Thursday even though the body had not summoned him to appear before them.
The Brazilian reportedly hoped to explain his actions, which left Motta, 31, with a broken nose after being butted by the Bastia striker following PSG's 2-0 win over the Corsican club in last Saturday's league encounter at the Parc des Princes.
However, he was suspended until Sept. 18, when the commission will hear all parties involved before deciding on a final course of action to take against the ex-Shakhtar Donetsk man.
"Brandao apologised. It was normal that he keep what he had to say for the Disciplinary Commission and not the TV or a talk-show," his lawyer, Olivier Martin, explained.
"Up till now, my client has said nothing to allow the media storm, which has laid into him for the last five days, to blow over."
PSG coach Laurent Blanc told media on Thursday that Motta could play in the French champions' Ligue 1 game at Evian on Friday wearing a protective mask.
