We are deeply saddened and shocked to hear of the passing of Justin Edinburgh.
Our heartfelt condolences and thoughts go out to his family and friends at this terribly difficult time as well as everyone that worked alongside Justin at Leyton Orient.
Edinburgh had just guided Orient to promotion back to the Football League after taking over in November 2017 as the club began an extensive rebuild.
“The success that Justin brought to Leyton Orient was incredible, but more importantly the impact he had on us all as a winner and a wonderful, inspirational human being will be his legacy and will stay with us forever,” said Travis.
Edinburgh began his playing career at Southend, winning promotion from the fourth tier, before joining Tottenham in 1990.
He made 215 appearances for the club and was part of the FA Cup and League Cup-winning teams in 1991 and 1999 respectively.
Tottenham tweeted: “We are deeply saddened and shocked to hear of the passing of Justin Edinburgh.
“Our heartfelt condolences and thoughts go out to his family and friends at this terribly difficult time as well as everyone that worked alongside Justin at Leyton Orient.”
It is with profound and utmost sadness that Leyton Orient announces its manager Justin Edinburgh has passed away.
Edinburgh also spent three years at Portsmouth before returning to his native Essex to end his playing career as player-manager of Billericay Town.
After spells with Fisher Athletic, Grays Athletic, Woking and Rushden & Diamonds, Edinburgh took charge of Newport County in 2011 and guided them to promotion back to the Football League after a 25-year absence.
Edinburgh spent over three years with the Welsh club before joining Gillingham in 2015, and a brief spell with Northampton Town followed.
Leyton Orient appointed Edinburgh in November 2017. He won 45 of his 82 games in charge, clinching promotion from the National League and a return to Wembley for the FA Trophy final.
The League Managers Association paid tribute to Edinburgh, with chairman Howard Wilkinson calling him a “true professional”.
My sincerest condolences to all your family Justin and to everyone at Leyton Orient . You’re a Champion that managed a team that played with your spirit.
Wilkinson said: “A hard-working man who became successful as a player at the highest level of the game and turned his love of football into a life-long career as a coach and as a manager.
“At a time when he should be celebrating the success of his team and preparing for the rewards of league football next season, he has been lost to the game and to his community too soon.”
Edinburgh is survived by his wife Kerri and their children Charlie and Cydnie.
