UEFA has opened disciplinary proceedings against Celtic over banners on display during their Champions League meeting with Shakhtar Donetsk.
A number of banners referencing the recent passing of Queen Elizabeth II could be seen in the Celtic end at Polish Army Stadium in Warsaw, where the sides played out a 1-1 draw on Wednesday.
Celtic now face potential sanctions, with UEFA confirming to Stats Perform on Thursday that disciplinary proceedings are under way.
However, Celtic s rivals Rangers will not face any punishment for defying UEFA s orders by playing the national anthem in tribute to the Queen before their 3-0 loss to Napoli.
A spokesman for the European football governing body said: The incident is not the subject of any UEFA disciplinary proceedings.
Her Majesty Queen Elizabeth II was honoured at Ibrox this evening with a minute’s silence, a display created by the Union Bears, and a rendition of the National Anthem.
