Championship One club York City Knights have parted company with head coach Gary Thornton.
The Knights have acted after failing to win promotion to the Championship through the play-offs, having finished the regular season as league leaders.
Chairman John Guildford said the club would now look to build a team capable of winning promotion next year and then establish itself in the second tier.
"It's a massive disappointment," Thornton told BBC Radio York.
"I knew what the expectations were, and that the club would face big challenges if it didn't get promoted. Sport is a results-driven business, and I guess if you're given targets and don't achieve them, you lose your job, but it doesn't make it any easier to take.
"I've had two terrific seasons and I wish the club all the best, I really hope they kick on. There are no vacancies out there at the moment, so I'll be putting my feet up for a few months."
York were relegated from the Championship in 2013 and were beaten 32-24 at home by Hunslet on Sunday in the Championship One play-offs.
Hunslet will play Oldham in the Grand Final.
