Sports website The Roar broke the rumour on Thursday night that Fifita, who is currently serving a suspension for an incident at a junior rugby league match, has his sights set on playing union in France.
The Roar report suggests Fifita will turn out in the centres for his native Tonga at the Rugby World Cup.
Sam Burgess and Sonny Bill Williams are rugby league forwards who have made the switch to the centres in union.
Fifita has a background playing junior rugby union and has been previously linked to the NSW Waratahs.
Here's the tweet from Steve Mascord's White Line Fever twitter account breaking the story.
