UEFA has opened disciplinary proceedings against Celtic following the pitch invasion by a fan during their Champions League tie against Paris St Germain.
The supporter raced onto the Parkhead pitch late in the first half with the hosts 3-0 down and darted towards 18-year-old superstar Kylian Mbappe.
He aimed a fresh-air kick at the former Monaco striker but failed to make contact before being whisked away by stewards.
On a difficult evening that saw the Scottish champions thrashed 5-0 - with Mbappe among the big-spending French club's scorers - this unsavoury incident only added to Celtic's woes.
Celtic have been charged with a count of "field invasion" and will have their case heard by the UEFA Control, Ethics and Disciplinary Body on 19 October, a statement from the European governing body said.
Celtic have already been fined 11 times in less than six years over fan behaviour issues ranging from pro-IRA chants to fireworks, crowd disturbances and illicit banners.
PSG have also been charged after their fans were accused of breaking seats at Celtic Park and will have their matter addressed at the same hearing as Celtic.
Hoops boss Brendan Rodgers has already expressed his frustration with Tuesday night's incident.
Other Hoops fans were unhappy with the disruption just before the interval and Rodgers said the Parkhead club will take its own action.
He said: "The crowd reaction said it all. It is disappointing at any ground that a supporter gets on to the pitch.
"I am sure the club will deal with that. It shouldn't be anything that we should see on a football field. The crowd in their reaction told you everything you need to know."
Meanwhile, Basel have also been hit by a UEFA disciplinary charge after their fans set off fireworks in their match at Manchester United.
Marouane Fellaini, Romelu Lukaku and Marcus Rashford secured the hosts a 3-0 win on a night when the Swiss champions' fans made themselves heard from the outset.
However, the use of fireworks before the Group A opener kicked off has led to disciplinary proceedings being opened against Basle.
The case will be dealt with by the UEFA control, ethics and disciplinary body on October 19.
St Etienne were fined €50,000 in March after their fans set off fireworks, in addition to charges for throwing objects and the improper conduct of supporters, in their Europa League last-32 clash at Old Trafford.
