Matty Russell has signed a new contract that will keep him at Warrington until the end of the 2017 season.
The 20-year-old former Wigan youngster, who impressed for Scotland at last year's World Cup, agreed a two-year deal in October.
Although his season has been affected by injury, the full-back has done enough in his six appearances to earn an extension to his contract.
"I felt settled here before I was even playing," he told the club website.
"This year I'm looking to cement my spot and keep up some good form.
"In the coming years I'd like to become a regular first-team player and make an impact in Super League and on the fans."
Coach Tony Smith added: "I think Matty has shown, in the short time that he has been here, what he is capable of and there is a lot more to come."
