Widnes Vikings have granted Brad Walker a release from his contract in order to take up a deal with a Super League club.
The Vikings academy product, who has been linked with Wakefield, had two years to run on his deal.
But the club has allowed him to move on after impressing last season, making 31 appearances.
“Firstly I’d like to thank everyone involved with Widnes Vikings for making my time here so special,” he said.
“I’d especially like to thank all of the people that work here and the fans for making me feel welcome since the day I arrived, and I’ll remember that forever.
“There’s a few people I want to personally thank, and that is Kurtis Marsh and Phil Finney. If it wasn’t for both of them spotting me up in Cumbria, and letting me move down here, I wouldn’t be where I am today. I will forever be in debt to them both.
“It’s always hard moving on but at this stage of my career, I think to have the chance to go back to Super League is something I couldn’t turn down.
“Again, thank you to everyone at Widnes Vikings, as well as the fans for their support over the years.
“This place took a chance on me and gave me my opportunity in professional rugby league, and I will never forget what this club has done for me.”
