Dewsbury have agreed to release back-rower Tommy Gallagher, who is expected to sign for League One side Swinton.
Changing and increasing work and family commitments meant that Gallagher was unable to make a full commitment to the club’s training schedule.
And following discussion, head coach Glenn Morrison and Chairman Mark Sawyer have agreed to Gallagher’s request.
In an open letter, Gallagher said: “This has been one of the toughest decisions of my Rugby League career.
“Due to additional work and family commitments it would have been almost impossible for me to attend training and match days.
“I have had a great two years at Dewsbury and have made friends for life, I will 100% miss the players, staff and club.
“I think I’ve played some of my best rugby over the last two years and it’s been hard for me to make this decision.
“I have enjoyed every minute of my time at the club and hope 2015 is a successful year for all involved.”
Gallagher scored 18 tries in 52 appearances for the Rams, and was the club’s Player of the Year in 2014.
Coach Glenn Morrison said: “We’re very disappointed to lose Tommy because he’s been an outstanding player for us during the last two years.
“He’s been first class on and off the field and it’s hard to replace players who have such a big impact at a club.
“It is disappointing for the players, and for the fans too, I’m sure, but we move on with our preparations for 2015 and a new era with great confidence.”
