Dewsbury have signed prop Chris Annakin from Wakefield on a two-year deal from 2020.
Annakin, 28, has made 77 first-team appearances for Trinity but has spent time on loan at the Rams over the last three seasons.
Dewsbury coach Lee Greenwood said: “Chris is a huge signing for us and I’m really pleased he has chosen to join the club permanently.
“I think he has seen what I’m trying to do here at Dewsbury and it’s great that he wants to be a part of it.
“I know he had other options but has enjoyed it here each time he has been on loan and to commit to us for two years shows how much he likes it.”
