Castleford captain Danny Orr will hang up his boots at the end of the current Stobart Super League season.
The 34-year-old half-back has taken the decision to end his playing career, even though he believes he could carry on, to become an assistant to current Tigers head coach Ian Millward.
Orr started out with Castleford - his hometown club - back in 1997 before going on to enjoy spells with Wigan Warriors and London Broncos, who were then known as Harlequins.
He returned to his roots in 2011 on a one-year deal but was persuaded to sign a 12-month contract extension to carry him into a 16th top-flight season.
"I feel as though physically I could do another year, but a coaching opportunity has come about and it is something I want to take up. There aren't mot many coaching jobs in Super League and I felt if I didn't take it now the opportunity may not be there in 12 months time," Orr said.
"I'll miss playing, I'm bound to. Though retirement happens to every player at the end of the day and I've achieved more things in my career than I could ever imagine.
"I've enjoyed every minute; I've been very lucky and very fortunate to play for three fantastic clubs and to be a professional Rugby player for so long, at such a high level. All of the supporters at Cas, Wigan and London have been fantastic with me and I'm grateful for their support over the years.
"Cas has always been my team since being a seven-year-old boy and this is where it all started for me and it is nice that this is where it will finish."
Millward hailed Orr - who made two appearances for Great Britain back in 2002 - as a "good servant" to the game and welcomed his decision to join his backroom staff.
"Danny has been a good servant to Rugby League and to Castleford," the Tigers boss said.
"He's a good clean natured guy and a local boy with great pedigree. He has a passion to remain involved in rugby league and I'm pleased he will come onto our coaching staff, assisting myself and Stuart Donlan; it will be a good starting point for him."
