Castleford Tigers front row duo Paul Jackson and Nathan Massey have both agreed new contracts.
Jackson, 32, and 22-year-old Massey have signed one and two-year deals respectively with the Tigers.
And Jackson, in his second spell with the Tigers, said: "I'm really pleased to be going round again - I'm really enjoying myself at Cas.
"I feel that I can still do it physically and I'm enjoying my rugby as much as ever."
Jackson, who rejoined the club from Huddersfield before the 2010 season having initially played for them in 2003 and 2004, added: "There's a good bunch of lads here and hopefully we can finish this season on a high and improve again next season."
Massey made his debut for Castleford in 2007 as a 17-year-old before loan spells at Featherstone, York, Gateshead and Keighley.
He has made 11 appearances in Super League for the Tigers so far this season and now hopes to add to that tally.
"I'm happy to be staying at Cas - I've come through the system here and I never really wanted to go anywhere else," he said.
"There's a really good platform here for the new coach to build on and I'm glad to be a part of the club's future.
"I've worked hard to get to the position where I am now, getting more Super League game time and hopefully from here I will be able to become a first choice regular in the side over the next couple of seasons."
