Craig Kopczak has signed a new two-year contract with Bradford Bulls, which will keep him at the club until 2010.
The prop is a product of the Bulls Scholarship and Academy systems and has made 12 first team appearances.
"I'm over the moon, it was up in the air last year but I just needed to get my head around things, knuckle down and get on with it," said Kopczak.
"Physically I've come on leaps, I've put in all the hard work and have been rewarded with this contract."
Kopczak made his first appearance for Wales at the end of last season and spent time on loan at National One side Halifax earlier this season.
Bulls coach Steve McNamara added: "It's great news for the club, Craig's a local Bradford lad who's really developed physically, has got very good skills and, in particularly over these last six months, really come on massively.
"He's turning into a big, powerful boy now and it's great that he's decided to stay with us here at the Bulls for another two years."
