The Scottish Premier League have decided to take no action against Celtic after completing their review on pro-IRA chanting.
The chanting was heard in a game against Hibernian on October 29.
Although no action has been taken the SPL have said they have taken "all reasonably practical steps" to prevent further behaviour of a similar nature.
"It is not disputed that a small number of Celtic fans engaged in singing and chanting in support of the IRA," a statement read.
"Such behaviour is unacceptable and unwelcome at SPL matches."
The Glaswegian club could still face action from UEFA after similar chanting was heard in a Europa League match against Rennes on November 3.
The UEFA hearing occurs this Thursday.
