Lawrence joined Bristol Rovers after leaving Cardiff City
Bristol Rovers have terminated the contract of their director of football Lennie Lawrence.
The club appointed the former Charlton boss in 2005 to partner manager Paul Trollope and the pair oversaw promotion to League One in 2007.
Rovers chairman Nick Higgs said: "When we first appointed Lennie Lawrence we realised that it was an arrangement that would not continue indefinitely."
Trollope is now in sole charge until an assistant manager is appointed.
Lawrence stated: "I am proud to have been associated with the progress at this club over the last four-and-a-half years.
"I have a fantastic relationship with Paul Trollope, which remains strong.
"I would like to take this opportunity to wish the board of directors, the management, the players and the supporters all the very best for the future."
Trollope told BBC Radio Bristol that he expected a new assistant to arrive at the Memorial Stadium in seven to 10 days time and said that the board were looking for "someone with experience of a higher level - either as a player or coach".
He added: "He [Lawrence] has been a fantastic professional to work alongside.
"His knowledge and experience has been a major factor in our success in the period we have worked together."
Lawrence, 62, came to the club after spending three years at the helm of Cardiff City.
On his appointment, then-chairman Geoff Dunford said Lawrence would review every aspect of the first team's structure, including player contracts, as well as a look into the youth sides and scouting operation.
Higgs added: "We want to keep moving this club forward, and we hope that Paul, with the help of a new assistant manager, can build a team capable of challenging for promotion."
The Pirates finished 11th in League One this season, after a play-off challenge faded in the final weeks.
