The young defender was shown a straight red card in Wednesday's 3-1 loss at Leicester and will be forced to sit out Sunday's game in West Yorkshire having started the Gunners' last three league matches.
Wenger has revealed that the long farewell to his reign as Arsenal manager has not been a completely enjoyable experience.
But on Sunday there were no less than two separate messages of support for the Frenchman as he leaves Arsenal after the final day of the season.
Pierre-Emerick Aubameyang equalized in the 53rd for Arsenal, but Jamie Vardy regained the lead for Leicester by converting a 76th-minute penalty and Riyad Mahrez made the points safe with a goal in injury time.

"We have gone through a season of ups and downs but they have always created something special and I would like that to come out in the last game by the way we play it". While Allegri has flirted with leaving Turin this season and had said that Champions League participation was a dealbreaker, it looks that he may now relent on that.
A sixth place finish - 37 points behind champions Manchester City - was a reminder how far Arsenal's standards had slipped in Wenger's final years.
"I see a bright future for my successor because the team has a good attitude and quality", he said.
"A European league will happen and it will be soon because it is a way for other clubs to fight against the Premier League".
"I will stay in football for sure. I am addicted and I don't think that can be cured", he said. "Either for Arsenal or someone else", Silva added. "But my last pain, the last big defeat, is that [Atletico Madrid]".
Handing one supporter his tie, Wenger basked in the warm glow of their applause for a few moments before disappearing into the sunlit evening.
