Castleford Tigers have extended the contract of ever-present second rower Oliver Holmes to the end of 2016.
The 21-year-old, whose existing deal was due to expire this year, has made 73 league appearances since making his debut for the Tigers as a 17-year-old in April 2010.
Castleford coach Daryl Powell said: "I am delighted that an outstanding young player who has risen through the club's development system has decided that his future lies with the Tigers.
"Oliver is a quality player and individual whose game is growing consistently and will continue to do so as he works so hard at his game."
Holmes said: "I'm happy with how I'm playing and that shows by being rewarded with the new contract. Daryl Powell has shown a bit of faith in me as I've started all but one of the games this year.
"There are still bits of my game that I'm looking to improve and that's what I'll be working on in training."
