Arsenal will appeal against Max Dowman's sending-off during Tuesday's Carabao Cup tie at Fleetwood.
The 16-year-old midfielder was shown a straight red card in the 85th minute after reacting to a heavy challenge by Fleetwood's Harrison Neal.
Although Dowman did not fully kick out, his foot did make contact with Neal.
The game finished 1-1 before League Two Fleetwood beat the Premier League champions 5-3 on penalties.
It was Dowman's second red card this month having also been sent off while representing England's Under-19s.
As Dowman left the field, Arsenal boss Mikel Arteta gave him a scathing look and made what appeared to be an angry comment to the youngster.
