Sean Long has left Salford Red Devils seven months after re-joining the club, according to owner Marwan Koukash.
Long previously spent 18 months as assistant coach, but left after Brian Noble was appointed head coach.
"The club has reluctantly agreed to Sean Long's request to leave the club with immediate effect," Koukash revealed on his Twitter account.
The former Great Britain scrum-half enjoyed a successful playing career in Super League with Wigan, Widnes, St Helens and Hull FC.
"I personally feel very disappointed," added Koukash.
"He knows why he is leaving and I wish him all the best. We won't take him back again."
