Castleford prop Grant Millington has signed a new three-year deal with the Super League League Leaders.
Millington, 30, was under already contract for 2018 but is now contracted to the Tigers until the end of 2020.
He said: “The club has been fantastic to me and my family. We love it here at Cas and this is home for us.
“I don’t think I could play for any other club. The club has transformed on and off the pitch since I joined and I’m proud to be a part of that.”
Millington has made more than 150 appearances for the Tigers since arriving from Canterbury Bulldogs back in 2012.
Coach Daryl Powell said: “Grant Millington has been outstanding again this season and I’m delighted that he has agreed to extend his contract to remain with the Tigers.
“His skill sets are second to none as a front row player and he has been integral in the way we have played the game over the last few years.
“I am confident that he will continue to improve and help to drive our standards for the remainder of this year and beyond.”
Castleford secured the League Leaders Shield with a win over Wakefield last Thursday and have since also signed centre Joe Wardle from Newcastle Knights.
