Young gun AJ Brimson had one simple goal for 2018 and everyone inside and outside the club can definitely say he has surpassed those goals.

The 19-year-old set himself the task of making his NRL debut in season 2018 and after he achieved that goal back in Round 10 against the Melbourne, he simply hasn't looked back.

Many questioned where he would play, many questioned whether he was ready for the week to week rigours of NRL football but the Runaway Bay junior simply hasn't missed a beat.

"It was my goal to make my NRL debut," Brimson said. "I definitely didn't think I'd get as many (games) as I have.

"I'm stoked to be playing but we're not where we'd hoped to have been on the ladder."

Although the result didn't go out way on Saturday afternoon against the Panthers, Brimson was a shining light, making his first appearance at fullback, replacing Michael Gordon who missed the match due to injury.

"I spent a bit of time at fullback over the last few years and played there a bit this season in Q-Cup, so I'm quite familiar with it.

"It's probably in defence that it's different but in attack you're really just playing as a third half."

Brimson will line up at fullback again this Friday night at Lottoland with Gordon set to miss the next couple of games due to that wrist injury.
