UEFA has opened proceedings against the Champions League match officials involved in the sending off of Istanbul Basaksehir assistant coach Pierre Webo which sparked a player walk-off, Europe's soccer governing body said on Thursday.

The match at Paris St Germain in December was halted after 13 minutes following an argument on the touchline over the red card shown to Webo and only resumed the following day after the four Romanian officials were replaced.

Webo, a former Cameroon international, said fourth official Sebastian Coltescu disrespected him by referring to him as "the Black one" and an investigation was conducted by a UEFA Ethics and Disciplinary Inspector.

"Proceedings have been opened against Sebastian Constantin Coltescu and Octavian Sovre for a potential violation of Article 11 of the UEFA Disciplinary Regulations," the governing body said in a statement.

Article 11 deals with general principles of conduct and focuses on breaches such as those which bring the game into disrepute.

Players from both sides, as well as the three new on-field match officials, took a knee before the game resumed the following day with PSG winning 5-1 at the Parc de Princes.

Honestly, I checked a bit more about this whole situation and it seem the assistant ref didn't meant to be racist. All in all, it feel like this whole situation was a misunderstanding that was blown out of proportion.

Yes, and the players could even be found guilty of leaving the pitch because of that. Hope it doesn't happen but still. Don't scream racism too fast

Everything now standardized to American definition of racism. N word in many countries not even a slur or racist remark, but description of the color, merely academic ( biological) definition of the the people that are colored black, and in the end entire Country called by it. Americans took that word and perverted it into racist connotation then somehow convinced the world that it became world wide standard for racist slur and not use it. Many languages should find another word for the word that resembles N word.

World has lost its marbles.

@Marcus Have to agree with you, heck, the FA banned Cavani from 3 game because he greeted another player in a way that could be seen as racist even though in their culture, its not at all. Ridiculous. Really wish they focused on real case of racist instead of persecuting player who haven't insulted anyone.

@Marcus, great point, I was missing the way to characterize why it was wrong the BLM interpretation to the European context. Because it is americanized. Exactly, spot on

The players should be punished accordingly for leaving the pitch without good reason. There was zero racism from the match officials and possible racism from the bench

Yes I actually agree with that in perspective, the players should be punished for leaving the pitch, they left because of a political issue and for image and fuss
