Manchester City could face a sanction after supporters booed the Champions League anthem ahead of Wednesday's 2-1 victory at home to Sevilla.
UEFA has opened disciplinary proceedings over the alleged "disruption of a competition anthem" -- under Art. 16 (2) (g) -- after its match delegate included the incident in his report.
A UEFA spokesperson confirmed to the Daily Mail that its Control, Ethics and Disciplinary Body will hear the case on Nov. 19.
However, the governing body stressed that the Premier League club would not necessarily be punished.
A UEFA statement in The Guardian read: "Please note that the incident was reported by the match officials, therefore a case was opened.
"This does not necessarily mean that a sanction will be imposed."
City fans have protested against UEFA at Champions League matches over the past year in protest at the financial fair play punishment meted out to the club by UEFA in 2014.
City were fined £49 million, hit with a transfer spending cap of the same amount and forced to limit their Champions League squad last season to 21 players rather than the regular 25.
Their disgruntlement with UEFA grew when a match against CSKA Moscow in the Russian capital last October was ordered to be played behind closed doors because of the behaviour of home fans. A number of City fans had already paid for tickets, travel and accommodation and felt they were being unfairly punished.
An organised boycott of the anthem was arranged in conjunction with Bayern Munich fans, who had a similar issue over a game in Moscow, prior to a game against the Germans last December. Both sets of supporters turned their backs during the anthem.
City manager Manuel Pellegrini this week refused to criticise supporters over the matter.
The Chilean was asked before the Sevilla game if the continued booing might be affecting his players in creating a negative atmosphere before games.
Pellegrini said: "I think we always have in the Etihad the atmosphere we need in Champions League, Capital One Cup or Premier League. We always feel the fans are behind the team and they always support us a lot.
"I don't think the atmosphere is lower than what we need. It is a good atmosphere."
