NSW skipper Boyd Cordner appears increasingly unlikely to play in State of Origin III after for the second time this camp he missed his expected return to the training track.
The back-rower has yet to train with the Blues side since entering camp on Monday and will on Sunday face D-Day as he attempts to prove he's recovered from an injured calf muscle.
Cordner continues to insist he will be fit for next Wednesday's game three at Suncorp Stadium however was once again an on-looker at Blues training at Coogee Oval on Friday.
He had previously targeted sessions on Thursday and Friday as the opportunity to show he had overcome the calf strain suffered in their series-clinching game two victory.
He looked hampered as he did fitness drills under the watchful eye of Blues trainer Travis Touma but insisted he was good to go, only to be held back by NSW medical staff.
Sunday's opposed session against the NSW under-20s at Allianz Stadium now shapes as key to his chances of being cleared to play.
"It's fine mate, everything's going to plan, I'm happy with it," Cordner said.
"I've been feeling fine all week, I've been itching to get out there and train with the boys.
"I have to listen to the medical staff, they've got a plan in place for me and everything's going well for me, I'm ticking every box, I'm feeling sweet.
"I wanted to do more today but I just had to trust the medical staff."
Tariq Sims again trained in Cordner's left back-row spot and is set to play there if the captain is ruled out, with 18th man Ryan James waiting in the wings to come onto the bench.
The Blues have one final session in Sydney on Sunday before flying to Brisbane where they will hold Tuesday's captain's run - usually a light session which can sometimes last only 15 minutes.
Blues five-eighth James Maloney also failed to finish Friday's session and appeared to grab at his hamstring however he told AAP he was not in doubt.
"It was just an early rest," Maloney said.
"I'm getting old. We were nearly done so it's all good."
