It wasn't a deal-breaker but AJ Brimson admits a return to Gold Coast's spine was a sweetener after he added at least another four years to his NRL life at the Titans.

The 26-year-old was already on the books until 2026 but on Thursday confirmed a monster extension until 2030.

In the club's system since he was 15, the four-time Queensland State of Origin talent never wanted to leave.

But he said a return to fullback after a brief experiment in the centres earlier this season had helped ease his mind.

"I had a chat to Des (Hasler) and I don't think I'll be going back to the centres," he said.

"Whether it's (No.) six or one, wherever fits in the best.

"I've never had too much doubt in my mind I wanted to be here long term."

Brimson (groin) will miss Sunday's clash with Brisbane and is slated to return in round 18, seven games from now.

But he said on Thursday he could be just four weeks away from his latest injury comeback.

"Hopefully, but it's a play-it-by-ear thing," he said.

The Titans (2-8) lost their first six games under new coach Hasler but have found some resolve with a 2-2 record since, the losses by two and four points.

They've also been beaten by one and four points this season.

Brimson acknowledged their rough start to life under Hasler but said captain Tino Fa'asuamaleaui's (2033) long-term deal and David Fifita's (2026) recent commitment, after initially signalling his intent to join the Sydney Roosters, had encouraged him.

"I can just see brightness coming in the future," Brimson said.

"Good young squad, players that want to stay here ... hopefully other boys see what I'm seeing."

Brimson laughed when asked how his body, which has copped its share of injuries, would hold up in 2030.

"That's the question," he smirked.

"No, it'll be good; I've had all sorts of different injuries and never really been impacted by them (long-term) in a negative way."
