Oldham coach Scott Naylor will leave the club when his contract expires at the end of this season.
Naylor is currently one of the longest-serving coaches in the British game, having been at the Roughyeds for seven seasons.
As a player, Naylor made over 130 appearances for Wigan, Bradford and Salford. He earned four caps for England.
Oldham chairman Chris Hamilton commented: “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.
“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.”
