Former New Zealand captain Benji Marshall is poised to switch codes after asking to be released from the final two years of his contract with Wests Tigers.
Talks between the club and player's management reached a final stalemate on Monday, with the Tigers unwilling to grant Marshall the lucrative contract extension he sought.
The 28-year-old's request for a release needs to be ratified by the Wests Tigers board but that appears to be a formality.
Marshall has played 193 matches for Wests Tigers and is their all-time leading points scorer.
"We are extremely disappointed to receive the news as we believe that we have been exceptionally generous to a player that has given us wonderful service over a number of years," said Wests Tigers chief operating officer Grant Mayer in a statement.
"Benji has obviously made a decision that he believes is right for himself and his family. All we can do is thank him wholeheartedly for what he has done for not only the club but the game as a whole.
"Benji Marshall in the eyes of all Wests Tigers supporters is a superstar and we have no doubt he will continue to support the club from afar."
Japanese and French rugby union appear Marshall's next best options after Super Rugby, with a stint in the English Super League appearing unlikely at this stage.
