David Luiz has been ruled out of Arsenal's Europa League match with Rapid Vienna on Thursday due to the cut he sustained in a head clash with Wolves striker Raul Jimenez.
Arsenal have come under intense scrutiny for allowing Luiz to play on at the weekend after he was involved in a nasty clash of heads with Jimenez, who has since had to have surgery on a fractured skull.
The club insisted they followed all protocols before sending Luiz, who had blood seeping through a bandage throughout Sunday's game before he was substituted, back onto the pitch against Wolves.
