Paris Saint-Germain and Istanbul Basaksehir's UEFA Champions League match was suspended on Tuesday after both sets of players left the pitch following allegations of racism against the fourth official, Sebastian Coltescu.
"Following an alleged incident involving the fourth official, the match was temporarily suspended," UEFA said in an official statement at the time.
"After consultation with both teams, it was agreed that the match would restart with a different fourth official. UEFA will thoroughly investigate the matter and further communication will be made in due course."

The walk-off occurred after Basaksehir's assistant coach Pierre Webo was shown a red card in the 14th minute, with it being alleged that Cotescu used offensive language when describing the former Cameroon international.
"The black one over there. Go and check who he is. The black one over there, it's not possible to act like that," the Romanian official is reported to have said by Reuters, as translated.
After leaving the pitch, Basaksehir's players subsequently refused to return from the dressing rooms as a result of the incident, following which the decision was made to suspend the tie until Wednesday night.

UEFA has confirmed that the match will resume on Wednesday night, with a new set of officials taking charge of the encounter.
