Wigan Warriors winger Iain Thornley is to join Hull Kingston Rovers on a two-year deal ahead of next season.
Thornley, 23, is currently on loan at Salford Red Devils for the rest of the 2015 season, having spent much of the campaign recovering from a knee injury.
The deal has disappointed Warriors chairman Ian Lenagan, who says he was offered a similar deal by them.
"Iain made the decision that money is the single most important facet of what he is looking for," Lenagan said.
"He's entitled to do that. From our point of view, we're a little bit irritated at the lack of loyalty, having taken care of him so well over the last 18 months, but players have to look after themselves as well and he's made this decision," he told the club website..
The former Sale three-quarter returned to action on dual registration at Workington Town after recovering from his injury before moving to Salford before the deadline.
Prior to the lay-off, Thornley was a key figure in Wigan's 2013 Challenge Cup and Super League Grand Final victories.
"I've ticked all the boxes coming back from injury and I've been playing quite a bit on 'dual reg'," he said.
"I'm only 23 but I've played in cup finals, Grand Finals and big play-off matches, so hopefully I can bring that experience with me and make a good impression.
"I want to keep it simple when I get over there, get used to everybody and hopefully nail down a starting spot."
