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lost their appeal to overturn David Luiz's red card against Wolves - but a ban for Southampton's Jan Bednarek has been rescinded.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 Wolves, while Bednarek was adjudged to have fouled Anthony Martial in Saints' loss at Manchester United.

An Arsenal statement said the club was "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, Luiz, 33, 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 pitchside monitor.

Luiz will now miss Arsenal's Premier League game at Aston Villa on Sunday.

Arsenal boss Mikel Arteta said earlier on Thursday that he was "very hopeful" that the decision would be reversed.

"I'm very hopeful. That's why we put the appeal in. We went through all the images and we think the red card should be overruled. That's why we appealed," said Arteta.

"We know the law, for me its more about the decision and what happens in that instance.

"He was on the side of the player that completely changes the angle, the purpose and the player's ability to finish the action but its still a similar action. I think they will look at it."

Meanwhile, Southampton boss Ralph Hasenhuttl felt that the decision to overturn Bednarek's sending off in the 9-0 defeat at Old Trafford was the correct one.

"I knew that Jan was not guilty for having made a foul because I saw the scene after the game so it was the only possible decision for me," said Hasenhuttl.

Mike Dean was the referee for Saints' defeat at Manchester United and the club have requested that neither he or Lee Mason, who was the fourth official, officiate their games in future.

Dean initially only awarded a penalty to Manchester United but dismissed Bednarek after being instructed to watch replays of the incident on the pitchside monitor by video assistant referee Graham Scott.
