The O’s will end their Final Third Development League campaign with a home encounter with Gillingham on Thursday (1pm kick-off).
The game will take place at Orient’s training ground – Old Chigwellians – with entry free of charge, though car parking spaces are limited.
Last time out in the Development League, a youthful O’s side held AFC Wimbledon to a goalless draw on April 12.
