according to a Romanian journalist they had on the 4th ref was trying to get the main ref to send off assistant Pierre Webo by saying "the black over there, it's the black over there, his behavior is not allowable" (and he used the Romanian word for black, which is negru). Then Webo got really heated, and the ref gave him a straight red, while the whole Turkish team started protesting

They've switched out the racist with a VAR ref, but the PSG players are saying they won't come back on until the Basaksehir players say they're OK with resuming play, so I don't think this can lead to a forfeit decision
