David Fifita has agreed to join the Sydney Roosters after opting to walk out on Gold Coast at year's end and turn his back on three-time defending premiers Penrith.
Fifita told Roosters officials on Thursday he would take up a four-year deal with the NRL club, worth close to $3.3 million over four years.
The signing coup will help the Tricolours replace some of the X-factor they lose with the impending departures of Joey Manu and Joseph Aukuso-Suaalii this year.
Veterans Luke Keary and Jared Waerea-Hargreaves will also finish up in the NRL this year, leaving the Roosters without 1,000 games of experience.
"You want quality players, and [Fifita] is a quality player," Roosters lock Victor Radley told AAP on Thursday.
"He's got the footwork, he's a powerhouse. Fast. You don't have many players that do all those things.
"He's got the X-factor."
The news comes as a blow to both the Titans and Panthers.
The superstar second-rower had met with Gold Coast officials on Wednesday night, before officially confirming he would not activate the final two years of his contract there.
Coach Des Hasler insisted on Thursday he did not feel personally slighted by Fifita's decision, and denied he was abandoning ship.
Re-signed to the Titans last year when Justin Holbrook was in charge, Fifita's decision to exit the club comes after a 1-7 start to begin this year.
"I think that is unfair to say that he is abandoning the ship," Hasler said.
"He has made a decision. It is not about abandoning ships. Everybody knew what was on the table.
"Not at all [do I take it personally]. It is a decision Dave has made. We move on and keep playing.
"It is disappointing, but it is all a part of the game and part of the theatre. It is part of the football merry-go-round that footballers come and go all the time."
Fifita's exit will free up the Titans' salary cap from next year, and offers a chance to spend big on their next playmaker once Kieran Foran retires.
