But according to Fox Sports Australia, Fusitu'a stayed back for the birth of his child, leaving fans baffled by the supposed news.
"Fusitu'a was granted permission to stay in Auckland for the birth of his first child," said a Fox Sports reporter.
The video of the gaffe was shared on Twitter by David's wife Eden, who was quick to correct the news report.
"David Fusitu'a has not had a child. Lol," she wrote on Twitter.
The 25-year-old centre will see out his 14-day quarantine in Sydney on his own before joining the team in Gosford where the new team will be based for the remainder of the NRL season.
Warriors coach Stephen Kearney said Fusitu'a will miss at least the first three games of the season restart as he'll need time to get back to full match fitness.
However, Kearney said he was happy with the progress of the rest of the team ahead of the May 28 start date.
"I'm very pleased on the back of last week, with the way the boys came back from the lockdown period," Kearney said.
"Also, the work we put in last week, we've had two really good days' training this week. So we're tracking along in the right direction. We've got a couple of areas we need to keep working on and we'll continue to do that."
