The Champions League game between Paris Saint-Germain and Basaksehir was postponed when players walked off the field after alleging that fourth official Sebastian Coltescu of Romania used a racial term when identifying an assistant coach. Players from the Turkish team were furious on Tuesday after assistant coach Pierre Webo was shown a red card by referee Ovidiu Hategan of Romania at Parc des Princes, saying Coltescu had used a racial term to describe Webo, who is from Cameroon, before he was sent off. Basaksehir substitute Demba Ba demanded that the fourth official explain himself, while PSG players Neymar and Kylian Mbappe also demanded an explanation. Basaksehir coach Okan Buruk said "you are racist" to Coltescu.

The scored was 0-0 when the incident took place about 15 minutes into the match. UEFA said the match would resume on Wednesday evening with new officials. "Following an incident at tonight-s UEFA Champions League match between Paris Saint-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," UEFA said late Tuesday. "A thorough investigation on the incident that took place will be opened immediately," it added. Television footage captured the exchange between the fourth official and the referee, with Coltescu telling Hategan that Webo should be reprimanded for his behavior on the sidelines: "Go and give it the red card to the Black one, this is not possible tolerable, go and identify him, go verify, the Black one over there," Coltescu allegedly said, in Romanian, about Webo. Webo was enraged and was heard to repeat at least six times "Why you say negro?" as he sought an explanation from Coltescu.
