York City Knights prop Jack Aldous has agreed a new two-year contract to keep him at the club until the end of the 2014 season.
The 21-year old joined York permanently at the start of the current campaign after a brief loan spell from Hull FC last year.
Knights general manager Ian Wilson said: "He has been a consistently good performer all season.
"He also has a fantastic attitude and is the type of player that we want."
He added: "He has his best years ahead of him."
Aldous joins captain James Ford, props Adam Sullivan and Nathan Freer, hookers Jack Lee and Harry Carter and back rower Ed Smith as players under contract for 2013.
