Quin Snyder has resigned as coach of the Utah Jazz after eight seasons in charge.

Snyder was appointed as head coach of Utah in 2014, signing a three-year contract before extending his deal twice to prolong his stay in Salt Lake City.

The 55-year-old transformed the Jazz into a competitive playoff force, reaching the postseason for the last six straight seasons, although they have not progressed past the conference semi-finals in that run.

Snyder was the joint-third longest-serving coach in NBA, alongside Golden State Warriors' Steve Kerr, who trails Miami Heat's Erik Spoelstra and San Antonio Spurs' Gregg Popovich.

Having overseen a period of change in Utah, Snyder departs with the second-best winning record of any Jazz coach after boasting a 372-264 regular-season record.

"Quin Snyder has embodied what Jazz basketball is for the last eight years," said Jazz owner Ryan Smith.

"The tireless work ethic and attention to detail Quin displayed each day is a testament to the professional he is. I have nothing but admiration for Quin and respect his decision.

"We thank Quin and Amy from the bottom of our hearts for all of their contributions to the state of Utah and the Jazz and wish them nothing but the best."

Reports suggested Utah were intent on agreeing a new contract with Snyder, who is said to want to take a season's break to recuperate before he considers a new coaching role.

"At the core, and what drives me every day is our players and their passion for the game, their desire to constantly work to improve and their dedication to the team and the Jazz," Snyder said.

"I strongly feel they need a new voice to continue to evolve. That's it. No philosophical differences, no other reason. After eight years, I just feel it is time to move onward.

"I needed to take time to detach after the season and make sure this was the right decision. I greatly respect and appreciate Ryan, Danny [Ainge] and Justin's [Zanik] discussions regarding moving forward together, I just know it is time.

"I am forever appreciative of all the players, coaches, partners, and people I have worked with at the Jazz. Your sacrifice, your kinship have made this an incredible and special experience.

"Amy and I are so grateful for our time here as it has been just a tremendous place to raise our family. Thank you to our always supportive and passionate fans. We only want the best for you and to see you raise a championship banner."
