Celtic face a Scottish Football Association charge over an alleged offensive banner among their fans in their pre-season friendly with Norwich.
The SFA on Thursday issued a notice of complaint alleging four rule breaches over the banner relating to Rangers, which appeared in the Celtic support in the July 24 contest at Parkhead.
The SFA charges allege Celtic have fallen foul of the rules by failing to prevent fans from bringing the banner into the ground and displaying it.
The club are also accused of failing to deal effectively with an instance of unacceptable conduct, "by allowing spectators to retain possession of the banner after it had been initially displayed, which allowed them to display the banner on a second occasion during the above match".
