The 18-year-old winger could be an option from the bench for Mikel Arteta this weekend with Gabriel Martinelli suspended.
Martinelli picked up a red card in the 1-0 win against Wolves at Molineux after being shown two yellow cards in the same phase of play.
Emile Smith Rowe is expected to take the Brazilian's place in the starting XI, while Ivory Coast international Nicolas Pepe is also in consideration for selection.
But teenage forward Hutchinson - whose style of play has been likened to Manchester City ace Raheem Sterling - could be handed a Premier League debut should he make the matchday squad.
According to Arsenal youth blogger Jeorge Bird, the England youth international has been training with the senior side this week.
He tweeted: "Omari Hutchinson has been training with the first team.
"With Martinelli suspended at least one academy player will be on the bench v Brentford."
