Promising youngster Nick Rawsthorne has signed with Hull FC until the end of 2019.
Rawsthorne joined the reigning Challenge Cup holders in the off-season from Championship side Halifax on a one-year deal and will remain in East Yorkshire for a further two seasons.
The 21-year-old is currently on loan at Leigh and has also spent time at York City Knights and Doncaster.
Hull boss Lee Radford said: “I’m really pleased to have extended Nick’s contract – it is great news for us.
“The coaching staff have been really impressed with his development this season and we are looking forward to that continuing with us over the next couple of years.
“To think this was Nick’s first full-time pre-season with us and to see the progress he has made over the course of the season has been very pleasing.
“We’ll be looking to make some real strides with him physically which will no doubt benefit his game massively.”
Rawsthorne added: “I’m really happy – it’s what I’ve worked for ever since I signed and it’s big for me to get the new deal.
“I’ve been wanting to prove myself to ‘Radders’ and I’ve been happy with how it’s gone. I’ve still got a lot to work on and it’s been challenging, but I’ve enjoyed it and I’ll be looking to push on further.
“Making my debut was another goal of mine as well as earning a new contract which I’ve achieved and now it’s about setting myself some new goals and making a push to play more games in the first-team moving forward.”
