Wakefield have signed loose forward Brad Walker from Widnes on a two-year deal.
The 21-year-old came through the academy at the Vikings, making 40 appearances for the first-team club.
Walker will remain at Trinity until at least the end of the 2021 season.
Wakefield coach Chris Chester said: “I’ve been particularly impressed with him at Widnes where he played over 30 times for them last year.
“He’s a tough loose forward who’s got plenty of skill with the ball and I’ve been impressed with him during his first week in training.
“Brad will be spending time at Newcastle Thunder in 2020 which will give him the opportunity to get regular game time.
“I’m looking forward to seeing him develop and watching him in the red, white and blue in the future.”
Walker added: “I’m over the moon to be joining Wakefield.
“I’ve always wanted to play Super League and it’s been my aspiration since I was a young kid, so I’m overwhelmed to get the chance to play for Wakefield.
“I’m a ball-playing loose-forward. I’ve always looked up to Sean O’Loughlin and I want to develop into that sort of player. I just really enjoy getting my hands on the ball.”
