Warrington Wolves second row George King has signed a one-year contract extension until 2017.
The 20-year-old forward made 19 appearances this season and scored his first try in the Challenge Cup win over Leigh in June.
The former Huddersfield youngster, whose brother Toby also plays for Wire, spent time out at North Wales Crusaders earlier this season.
"George has really come on this year," said head coach Tony Smith.
"We believe he has a really bright future and will hopefully go on to bigger and better things here at Warrington."
Wolves have also announced that 18-year-old centre Harvey Livett has signed his first full-time contract.
