Dewsbury have signed front-rower Harvey Hallas from Keighley for the 2019 season.
The 21-year-old came through the academy at Wakefield Trinity, before joining the Cougars in 2017.
Hallas was originally a back-rower but has moved into the middle over the last couple of years.
On joining the Rams, Hallas said: “Being at Keighley last year in league 1, I just thought I wanted to push myself a little more, and I think the Championship and at the Rams is a good place to do that.
“I think the club will have a good ethic and I know they want to try and achieve more than what other clubs are doing.
“I think it is a good place to push myself, and it is the next step in my career going forward.
“I am only a young lad really at 21, and so I will be coming up against people who have been in Super League, or are knocking on the door of the top division. It is going to be a massive physical challenge for me, but I am really up for it. I know mentally and physically it will be a challenge.”
