Arsenal goalkeeper Bernd Leno was sent off for a bizarre deliberate handball that saw his side go down to nine men in their chaotic defeat by Wolves.
The German joined David Luiz in players to be given their marching orders by referee Craig Pawson, as goals from Ruben Neves and Joao Moutinho earned a 2-1 victory for the home side.
With Arsenal chasing the game in the final 15 minutes having thrown away a 1-0 lead, any hope of getting a result vanished as Leno came rushing out of his goal but appeared to misjudge the ball's bounce.
