Castleford centre Jake Webster has signed a one-year contract extension with the Super League leaders.
Webster has been rewarded for his fine form this season and will now remain with the Tigers until 2018, with the club also holding an option to extend his deal by a further year.
The 33-year-old former New Zealand international has been instrumental in Castleford's rise to the summit of Super League and Webster says he is happy to commit his future to the Yorkshire club.
"I'm really excited to have signed a new deal here with the Tigers," Webster said. "I really could not have seen myself putting another team's jersey on.
"I'm really happy with how things are going this year and how they have gone since I managed to get myself injury free.
"The club has been great to me and the fans are second to none. They drive me to play the way that I do and I hope I can just be around them and this club until the end of my career."
Castleford head coach Daryl Powell believes Webster can help to provide the club's youngsters will valuable experience as he enters the closing stages of his playing career.
"Jake has shown this season that he is still a very good player in all aspects of his performance," Powell said.
"He is a much more durable athlete than he has been in the past and his skill sets and experience are a key part of our form so far this season.
"This new deal gives Jake a chance to continue to drive his standards and support the young players at our club."
