Dewsbury have signed Welsh back-rower Rhys Davies on a one-year contract.
The 23-year-old joins the Rams after impressing on a trial period with the Championship club.
Dewsbury coach Lee Greenwood commented: “Rhys fully deserves to be rewarded after working hard and impressing in training.
“Through a combination of playing for us, Coventry Bears on dual-registration or for Hull KR reserves, he will get plenty of game time which will see him develop.
“I’m looking forward to seeing him play at Keighley in our next friendly and he will be competing for a shirt in the 17 like everyone else. He has the potential to play at Championship level if he really wants it.”
