Frizell's latest blow – separate to the one he needed a pain-killing injection to subdue to play in Origin II – has raised the prospect of his St George Illawarra teammate Jack de Belin making his NSW debut in one of the most anticipated interstate showdowns in history.

NSW officials received the results of scans on Frizell minutes before naming an unchanged line-up for the State of Origin decider on Wednesday week with Frizell jumping skipper Boyd Cordner (calf) to the front of the doubtful queue.

The Dragons updated their fans on Monday on the prognosis of Frizell and NSW centre Josh Dugan (quadriceps), both of whom failed to finish the Red V's loss to the Titans last Friday night.

Frizell is unlikely to be able to train properly until later in the week – like Cordner – hampering Daley's preparations as the Blues seek to rebound from a demoralising Origin II loss.

But he remains desperate to atone for NSW's game-two meltdown despite wincing when colliding with Gold Coast defenders while on club duty.

"Tyson came from the field on Friday night with a rib injury which occurred upon impact with the ground," Dragons head of athletic performance Nathan Pickworth said. "He had a scan over the weekend and it has revealed a new rib cartilage injury.

"We advised the NSW Blues medical staff of the results with indications on Tyson's playing and training capacity for Origin III and the importance of Tyson's welfare in their training and playing plans throughout this camp."

James Tedesco (ankle) is considered a certain starter despite not playing for the Tigers since Origin II.

But Daley is happy to wait until much later in his side's Kingscliff camp before making a decision on Frizell and Cordner, his damaging edge back-rowers who have been dynamic at various stages throughout the first two games.

"There's some concern there, but we thought we would give the guys an opportunity to prove their fitness," Daley said. "We started with this team, we want to finish with this team."

Daley was a member of the last NSW side to keep the same squad in all three games when the Blues swept the Maroons in 1996.
