McGeady (left) been in and out of Strachan's staring line-up this season
Aiden McGeady's agent says the midfielder remains committed to Celtic, despite contesting the fine and suspension imposed on him by the club.
"He has been suspended for two weeks," David Holbrook told BBC Sport. "That's not the same thing as never playing for the club again."
Celtic took action claiming a breach of club discipline after a reported fall-out with manager Gordon Strachan.
But Holbrook said he knew nothing of the need for a written apology.
"Neither Aiden or the club have made we aware of any request from the club, or indeed anyone else, for a written or verbal apology," said the Republic of Ireland winger's agent.
Aiden plays for Celtic. He loves Celtic and wants to be part of the cause
Agent David Holbrook
"I have been familiarising myself with the in-house appeals process and disciplinary process and I can't see anywhere that there is any aspect of it that would allow the demand of an apology."
McGeady and Strachan reportedly had a disagreement following a 4-2 defeat by Rangers at the start of the season.
And Celtic took the present action after a dressing-room argument that followed Saturday's 1-1 draw at home with Hearts.
Holbrook, who is seeking legal advice via the players' union, would also be investigating whether Celtic were within their rights to impose both a two-week suspension and a fine of two weeks' wages.
And, while he hoped that the situation could be resolved quickly, he thought it possible that McGeady could serve his ban and have his fine taken from his wages before the appeals process was completed.
"I presume Celtic are acting as they are entitled to do and we are taking action as we are entitled to do," said Holbrook.
"There is a dispute, but that is not to say that the grievance will not be reconciled."
News of McGeady's censure came on Tuesday as Celtic completed the signing of winger Niall McGinn from Derry City.
However, Holbrook insisted that McGeady wanted to remain at the club he supported as a boy - and that he knew nothing of reported interest from clubs in England's Premier League.
"Aiden plays for Celtic," said the agent, when asked if McGeady wanted to play again for Strachan.
"He loves Celtic and wants to be part of the cause.
"He wants to play in the next match for Celtic. Obviously Celtic don't want him to play in it.
"No other club has contacted me. You would have to ask Celtic if any club has come in for Aiden McGeady as they don't need to tell me or Aiden."
Holbrook had previously said that McGeady had been left "shocked and disappointed" by the club's action, which he thought was "completely unjustified".
