City have until Monday afternoon to decide whether to appeal or accept an automatic three-match ban.
Boss Roberto Mancini said: "We will decide this morning. We talked yesterday and today we decide.
"We don't know what can happen if we appeal. Usually they reject an appeal.
"This could be a problem because after this game we lose three players, Yaya (Toure), Kolo (Toure) and (Abdul) Razak and we don't want to lose another."
