Sean Long is looking for a fifth coaching role in 12 months after bringing to an end his brief spell on the backroom staff of London Broncos.
The former St Helens and Great Britain scrum-half joined the capital club in the close season after their off-field issues were resolved by a move to Barnet.
However, the Broncos say Long was only ever used as a consultant, working one day a week in the capital, and he confirmed on his Twitter account that he has now left the club.
Long, who hung up his boots in August 2011, resigned as assistant coach at Salford Red Devils last April and then had a three-month spell at Wigan Warriors before ending the season as football manager at Featherstone.
He was also assistant coach of Samoa in the 2013 World Cup.
London have appointed Australian Joe Grima as the official assistant to head coach Tony Rea.
