St Helens have confirmed a swap with Gold Coast forward Zeb Taia joining Saints and Joe Greenwood heading to the Titans.
Former Catalans star Taia has signed until the end of the 2019 season.
Saints head coach Keiron Cunningham said: “We’re delighted to have signed a player of Zeb’s calibre and he will bolster our squad immediately.
“He is powerful, possesses a great offload and like our other signings this season, will bring big game experience to the Saints.”
Saints have allowed second rower Joe Greenwood to take up a contract in the NRL.
The 23-year old has agreed a deal after originally joining the Saints from Saddleworth Rangers in 2011.
“We wouldn’t want to stand in the way of any player wishing to ply their trade elsewhere and Joe has been given a good opportunity at the Gold Coast,” Cunningham said.
“It’s always difficult to lose a homegrown player and personally I will be sad to see him leave. I’ve worked hard with Joe to develop his game and help him grow as a person – and he has done just that.
“Hopefully, one day after a successful NRL career, he will pull on the Red V again.”
