Brailey, who has been rated a State of Origin contender by no less a judge than Danny Buderus, will miss up to half the season after rupturing his Achilles tendon last week in a freak training accident.

Randall, the 26-year-old Lakes United junior, has been earmarked to fill the dummy-half vacancy.

And while he has only 12 NRL games to his name, seven of which were off the bench, he has been in a league of his own during pre-season training, according to Newcastle's new physical-performance manager Hayden Knowles.

Knowles, who has worked at a host of NRL clubs over the past two decades, most recently with premiers Penrith, paid Randall an extraordinary compliment by labelling him the fittest player he has encountered.

"Chris Randall will out-work anyone," Knowles told the Newcastle Herald.

"I'm not just talking that up.

"I've spent the last few years with the Penrith Panthers, where I thought Dylan Edwards was the fittest rugby league player I've ever seen, and the most competitive.

"I've never seen anyone beat Dylan Edwards' fitness results, but I've just seen it with Chris Randall.

"I just love him.

"The way he trains, his work ethic and what it means to him ... he's just so fit. He is so fit.

"He stands out.

"I can't speak highly enough of him."

Randall, who made an NRL-record 71 tackles on debut against the Panthers in 2020, now has a window of opportunity to establish himself while Brailey is sidelined.

"I don't think he needed any extra motivation, because he's already so motivated," Knowles said.

"It's very unfortunate for Brails, but everybody here has so much trust in Chris Randall.

"And trust doesn't come easily. He gives you reason to trust him.''

Knowles dismissed suggestions that Brailey's season might be written off before he had even played a game.

"If you do the maths, he's coming back a few months into the season," he said.

"Some blokes are back are within five or five-and-a-half months. We still need to get all that confirmed by the surgeons, but he'll be back this year."

Brailey was awaiting surgery this week as his teammates travelled by bus for a three-week training camp in Armidale and Gunnedah.

"He's just a real pro," Knowles said of the former Cronulla hooker, who was one of Newcastle's co-captains last season.

"The poor kid was in tears. It means so much to him.

"And I dare say there were a few staff holding back tears too.

"Everyone was just shattered for him.

"But once you get past that, you just know that he's the most diligent professional and he'll handle it well and be back before you know it."
