The 23-year-old, currently on international duty in Australia with England, is a product of the club’s youth system. He has scored 72 tries in 128 appearances for the club, and now should remain at Headingley until the end of the 2019 season.
“I never wanted to play for any other club than Leeds and I am pleased we have been able to agree a new deal that keeps me here for the future,” he said.
“I have got a young family and the chance to be part of this team as we develop over the next few years is something I am very excited about.
“The Cup final last year was very special and it has whetted the appetite for what is to come in 2015.
“We were all disappointed that we could not get back to Old Trafford last season but I am sure that will drive us on in pre-season to make sure we are ready to go one better in next season.
2We have got a tremendous group of players at the Rhinos and a great coaching team and together I think we can achieve even more over the next few years.
“The last decade has been an incredible time for the Rhinos and it has been special to be part of that. Our challenge is now to build on that and continue that period of success in the years to come.”
