Australian stand-off Adam Mogg has requested to be released from the 20 months remaining on his Catalans Dragons contract.
The 32-year-old veteran, who played for Queensland in the State of Origin, has become homesick in Perpignan and has been offered the chance to return to his old club Canberra.
The Raiders are seeking cover for Test utility player Joel Monaghan, who has been ruled out with a thumb injury, and are negotiating the terms of Mogg's release with the engage Super League club.
"We heard on the grapevine that Adam hasn't been too happy over there so we have spoken to him," said Canberra chief executive Don Furner.
"It just comes down to whether we can work something out with Catalans. Hopefully we can come to some sort of arrangement."
Dragons' have been without Mogg, who is recovering from a knee injury, for their last two matches, but his departure would be a setback for Kevin Walters' side as they attempt to escape the basement of the league table.
"He's trying to negotiate a release," said Walters.
"It's not good news for the Dragons. He's been a terrific player for the club in his time here and he will be missed.
"I'm not too sure what's happening back in Australia but he's been over here four or five years and it can be difficult when you've not got the support of your family and friends."
Mogg has been a key player for Dragons since moving to the south of France from Canberra at the start of the 2007 season and making the Super League Dream Team that year.
The Australian qualified to represent France last year but withdrew from the 2009 Four Nations due to injury.
Catalans can draw some consolation from the fact his departure would open up a vacancy on their overseas quota as they seek a replacement for full-back Clint Greenshields, who is out for up to three months after breaking a leg in last Saturday's home defeat to Castleford.
Dragons were looking to sign Ulster rugby union full-back Clinton Schifcofske, an Australian of Polish descent, but may have missed out to Crusaders, who they will face at the Racecourse on Friday night.
"We're endeavouring to bring someone in but we have to wait for Adam to finalise things," said Walters. "It's happening all at once and we're starting to get a bit thin."
