Kyle Lafferty admitted letting himself and his club down after he admitted using sectarian language.
A video appeared on social media and resulted in a club fine for the player.
He is due to face a Scottish FA hearing in October.
Kyle acknowledges that he let down himself, his family, the club and the supporters.
According to the club, they imposed a substantial fine and that Lafferty will work with an anti-sectarian charity.
Kyle has committed to supporting the club's community projects, which will see him participating in educational initiatives, as well as serving Kilmarnock's 'Football for All' programmes on a weekly basis for the foreseeable future.
The SFA has accused Lafferty of not acting in the best interests of football and breaching a rule that forbids the use of insulting language, which includes references to the likes of ethnic origin, race, nationality, religion or belief.
SFA rules state that the punishment for the latter is a mandatory minimum 10- match suspension.
McInnes said he couldn't say for certain if Lafferty would play against Aberdeen.
Ian Baraclough stated that a back injury had been considered when the decision was made to withdraw him from the Northern Ireland squad.
The former Motherwell manager said that the incident was not the end of the international career of Lafferty.
