Castleford back-rower Matt Cook has signed a new one-year contract extension.
Cook, 32, has made 98 appearances since joining the club in 2015.
He previously played for the Tigers on loan from Bradford back in 2008.
Coach Daryl Powell said: “I’m delighted that Matt Cook has agreed to extend his contract.
“He has played some outstanding rugby league for us over the last few years and his form so far this season tells us he’s playing some of the best rugby of his career.
“I’m really looking forward to continuing to work with him this and next season.”
Cook started his career at Bradford before stints at Hull KR and London Broncos, where he was captain.
He said: “I’m really happy that the club have offered me the opportunity to remain a Tiger for another year and I am pleased to say that I have accepted. Castleford is a great club that I have been part of for almost five years now, I have made some great friends here, and under the boss have without doubt, played my best rugby.
“I am still itching for more success and silverware, and I believe being a Castleford player gives me the best opportunity to achieve that.”
