The Swede was dismissed for insulting referee Fabio Maresca, though insists he was misheard.
Milan's lawyer Leandro Cantamessa said, “It all depends on what Maresca writes in his report.
“If he has doubts on what he heard, he should write it, and the matter may have an unexpected and resounding twist.
“If the referee admits he was wrong, then Ibra could play the next game even if he was shown a red card in the previous game.
“If it doesn't happen, he could even get a one or two-match ban, but that would be so unfair.
“We can't appeal if he receives a one-match ban," the lawyer continued.
“There was a misunderstanding. There's nothing more to add. I heard what Ibrahimovic said, and I don't know what the referee heard, but I know Ibra didn't insult him."
