Head coach Scott Naylor will leave Oldham RL Club when his current contract expires at the end of this season.
He is currently one of the longest-serving coaches in the game, having been at Oldham for seven seasons.
Club chairman Chris Hamilton said: “Scott has been with us for a long time in Rugby League terms and has had a big influence over those years.
“But, like everything else, things come to an end and following the conclusion of this season we will both move on, parting on good terms.
“There is still an awful lot to play for this season and I know both Scott and the players will be fully focused on the remaining games. In the meantime the club will begin its search for a replacement.
“We hope to have our biggest crowd of the season at the Vestacare Stadium this Sunday for what should be a cracker of a game against Newcastle Thunder.
“The end of the season, which we all hope will be another successful one, will be the appropriate time to look back at Scott’s long spell in charge.”
