Arsenal have lost their appeal to overturn David Luiz's red card against Wolves - but a ban for Southampton's Jan Bednarek has been rescinded.
Gunners centre-back Luiz clipped Willian Jose's heel in the box in a 2-1 defeat at 2-1 defeat at Wolves, while Bednarek was adjudged to have fouled Anthony Martial in Saints' loss at Manchester United.
An Arsenal statement said the club were 'disappointed' with the appeal result.
Defender Bednarek will now be available for Saturday's trip to Newcastle.
The Gunners were 1-0 ahead when Luiz was judged to have fouled Jose and, because there was no attempt to play the ball the defender was dismissed and Ruben Neves scored the resulting penalty.
Craig Pawson was the referee in charge - and following a video assistant referee check the decision remained, although Pawson was not asked to review the incident on the pitch side monitor.
Luiz, 33, will now miss Arsenal's Premier League game at Aston Villa on Saturday.
