PSG handed race-row victim Pierre Webo a special jersey after the delayed Champions League tie with his club Istanbul Basaksehir.
Romanian fourth official Sebastian Coltescu may quit football rather than face a possible 10-match Uefa ban after both sides accused him of racism.
Coltescu sparked a walk-off after he allegedly identified Basaksehir coach Webo as “the black one” when asked by referee Ovidiu Hategan who to approach.
Webo was shown a red card but was on the bench for Wednesday’s tie – lasting 76 minutes due to its 14th minute abandonment on Tuesday – as Uefa suspended his ‘sending-off’ while they investigate racism claims.
And after PSG’s 5-1 win, the French champions’ supremo Nasser Al-Khelaifi acted to show the two clubs’ solidarity by giving the Cameroonian a No9 shirt with his name on it.
Players from both teams had warmed up in “No to Racism” T-shirts.
And they also took a knee alongside the new match officials from Holland and Poland.
But the fall-out from Tuesday night’s original tie continues.
Coltescu denied he had done anything wrong, telling Romanian reporters: “I just try to be good.
“I’m not going to read any news these next few days. Anyone who knows me knows that I’m not racist. At least, that’s what I hope.”
