Arsenal are reported to have lodged an appeal over Eddie Nketiah's red card in the 1-1 draw against Leicester City on Tuesday night.
The 20-year-old was shown his marching orders just four minutes after replacing Alexandre Lacazette.
He was first issued a yellow card for a foul on James Justin, but a second check on the VAR saw referee Chris Kavanagh brandish a direct red card to him.
The match ended in a 1-1 stalemate with Jamie Vardy's 85th minute goal cancelling out Pierre Emerick Aubameyang's first half strike.
