It came after a red card was shown to one of Basaksehir’s staff, apparently assistant manager Pierre Webo, with video footage emerging which appeared to show the Cameroonian accusing the fourth official of using racist language.
Basaksehir posted a message on their Twitter account which read: “NO TO RACISM #Respect.”
Video footage also showed Basaksehir striker Demba Ba remonstrating with the fourth official, Romanian Sebastian Coltescu, on the touchline.
Governing body Uefa said in a statement that the game would continue with a replacement fourth official, but more than an hour after the players left the pitch, it had still not done so.
Uefa confirmed soon after that the fixture would be completed on Wednesday with a different set of match officials following consultation with both clubs, while an investigation will be launched into the events.
The governing body said: “Following an incident at tonight’s Uefa Champions League match between Paris St Germain FC and Istanbul Basaksehir FK, Uefa has – after discussion with both clubs – decided on an exceptional basis to have the remaining minutes of the match played tomorrow with a new team of match officials. The kick-off has been set at 18:55 CET (5:55pm GMT).
“A thorough investigation on the incident that took place will be opened immediately.”
