Castleford hooker Ryan Hudson is to retire at the end of the season.
The 32-year-old former captain is in his second spell with the Tigers after stints at Wakefield and Huddersfield.
"I am ready for a change," he said. "My body feels okay but mentally I'm ready. I'm excited about the future. We've launched the elite rugby academy and I've also a few other options."
Castleford chief executive Steve Ferres said: "I'd like to wish Ryan a happy retirement and hope that he continues to be involved in our great game."
