He said: “The main thing that attracted me to the Rams was Glenn Morrison.
“I’ve only ever heard good things about him – plus he’s a back rower so hopefully he’ll be able to help my game.
“The fans can expect me to give 110%.
“The new league structure is really exciting for me as a player and I’m really excited about facing the Bulls and the Broncos, especially London, as my brother Luke has just signed for them. I’m really looking forward to taking on the challenges ahead as a Dewsbury player.”
Coach Morrison added: “I came across him when I was coaching the Wakefield 20’s and 18’s.
“I’ve kept an eye on him since then and he’s turned into someone I’m really looking forward to getting my hands on.
“He’s a good young player and he’s had a good upbringing after coming through the academy at Salford. He’s a very strong player too, he’s got good agility for a back rower and he can play good minutes as well.
“When we’ve played against North Wales this year he’s really stood out for them and our boys were coming off the field saying ‘that Adamson’s a good player!’
“He’s still a young kid so he’s got his best years ahead of him and if we can improve him we could have a real star on our hands.”
