Bradford have agreed to release Frank Winterstein before the forward has made his debut for the Super League team.
The Samoa international agreed a 12-month deal with the Bulls in October but returned home to Australia before the year was out after suffering a pectoral injury in a World Cup game with New Zealand.
The 27-year-old had treatment for the injury in Australia and has opted to stay Down Under following his recent wedding, with Bradford giving their consent.
Winterstein is now expected to take up a deal in rugby union and Bradford coach Francis Cummins insists he understands the player's decision given the ongoing off-the-field uncertainties at Odsal.
Cummins said: "Him and his wife have just got married and I guess, for a player who has in the past witnessed financial difficulties at other clubs, the uncertainty wasn't great for him.
"If an opportunity has arose elsewhere for him then we cannot really stand in his way, given the fact we are attempting to make cuts to our playing budget."
