Wakefield Trinity Wildcats coach John Kear will leave the club at the end of the season.
The Wildcats kept their Super League licence this week against the odds when Crusaders withdrew their application.
Kear told the club website: "I am a subscriber to the philosophy that coaching has a five-year cycle.
"Having joined in 2006, this is the time to seek a fresh challenge, thus coinciding with the club's new ownership and Super League licence."
Kear will remain in charge of Wakefield for their final five games, including Sunday's clash with Crusaders.
Chief executive James Elston said: "Having sat down with John this week all parties felt it was the right time to make a change.
"He has played a major part in the recent history of the Wildcats and I wish to place on record our thanks for what he has achieved since coming in to the post in 2006.
"There have been some testing times at the club throughout his campaign and John has always approached each situation with dignity and professionalism."
And Kear added: "My tenure with the Wildcats started with that unforgettable end-of-season run of four wins out of six to avoid relegation, further highlighted by the 2008 campaign with a club best-ever Super League finish of fifth and a highly creditable Challenge Cup semi-final appearance.
"Throughout the five years, the club has established itself as a mid-table side, this season being made onerous by financial crisis resulting in a crippling points deduction."
