Arsenal midfielder Max Dowman will miss three matches after the club's appeal against his red card in Tuesday's Carabao Cup defeat at Fleetwood Town was rejected.
The 16-year-old was shown a straight red card in the 85th minute for violent conduct after reacting to a heavy challenge by Fleetwood's Harrison Neal. Although Dowman did not fully kick out, his foot made contact with Neal.
The match ended 1-1 after normal time, with League Two side Fleetwood winning 5-3 on penalties to eliminate the Premier League champions.
Arsenal submitted an appeal on Wednesday, but it was dismissed, meaning Dowman will serve a three-match suspension. This is his second red card this month, having also been sent off while playing for England's Under-19 team.
As Dowman left the pitch, manager Mikel Arteta gave him a scathing look and appeared to make an angry comment. After the game, Arteta said: "When we prepared the context of the match, we were very clear on the things to respect, the things that emotionally we have to dominate. It was very clear."
The dismissal leaves Arsenal short on wing options, with Bukayo Saka, Christos Tzolis and Noni Madueke currently injured. The Gunners return to Premier League action away to Liverpool on Sunday.
