Collections will be taking place around Meadow Lane at Saturday's game against Barnet to raise funds for the Justin Edinburgh 3 Foundation.
The Foundation, set up by Justin's family following his untimely passing, focuses on raising awareness of brain and heart disease and promotes the use of defibrillators in health clubs and gyms.
Justin passed away in June after suffering a cardiac arrest only weeks after guiding Leyton Orient back into the EFL.
Rest in peace, Justin.
