The 18 year old has joined the O’s until March 27th and takes the experience of three Premiership games to the league one outfit.
He will go straight into Geraint Williams' squad for the game against Gillingham on Tuesday night.
Williams told the club's official website: "Aaron comes highly recommended to us by our northern scout and he trained with us on Monday morning and looked nice and tight. He's looking to get his chance with us."
