Paris St Germain and Istanbul Basaksehir sent a powerful anti-racism message before their rescheduled Champions League match at Parc des Princes as their players all took a knee.
The Group H fixture was halted on Tuesday night after 13 minutes, with both sets of players walking off the pitch 10 minutes later with the score at 0-0 after the fourth official, Romanian Sebastian Coltescu, was accused of using a racist term towards Basaksehir assistant manager Pierre Webo.
Webo, who had been sent off amid the incident on Tuesday, was allowed to take his place on the away bench, with his red card suspended while UEFA investigates what happened.
The governing body has announced the appointment of an Ethics and Disciplinary Inspector to look into the events and has said it will impose "appropriate sanctions" if the official is found guilty.
A new set of officials were in charge for Wednesday's game, with Dutchman Danny Makkelie appointed as referee.

The match restarted in the 13th minute with a free-kick to Basaksehir just inside their own half.
