Star centre Tom Trbojevic returned to Blues training on Thursday having sat out a session earlier in the week.
Trbojevic told NRL.com on Wednesday that he missed the session due to player load as he had gone around on Sunday for Manly. He said it had nothing to do with trying to protect his hamstrings.
Former skipper Boyd Cordner was also on hand at Blues training on Thursday to help out with preparations for Sunday's game.
Roosters forward Angus Crichton and Storm lock Dale Finucane are the new faces in the NSW 20-man squad for Ampol State of Origin II with Crichton to come from the bench and Finucane in the reserves.
Coach Brad Fittler has also included 18th man Api Koroisau and Campbell Graham in the squad.
Crichton, who missed the series opener through suspension, joined his Blues teammates in camp on Sunday.
Finucane returns to the Blues set-up after playing two of three games in last year's series.
The off-contract star missed the opening six rounds of the Telstra Premiership with a calf injury but has returned to help Melbourne reach top spot on the ladder in recent weeks.

Panthers forward Liam Martin has retained his spot on the bench after a week of uncertainty and following the withdrawal of Jake Trbojevic.
The Blues are otherwise settled ahead of their quest to clinch the series in Brisbane following a dominating 50-6 series display in Townsville.
The squad travelled to Kingscliff on Monday to begin preparations after the increase of COVID-19 cases in Sydney over the past week.
Fittler has promoted Junior Paulo to the run-on side to replace Trbojevic at prop with Crichton earning a recall on the bench.
Speaking on Channel Nine's Sunday Footy Show earlier in the day, Fittler said Finucane's recent form could not be overlooked.
"What I see now is he’s developing a passing game in the middle," Fittler said.

"He’s scoring tries through the middle and his defence is always awesome.
"If you see him off the field he’s the ultimate professional. I know there’s players that look after themselves but he is better than all of them.
"Getting him in the squad somewhere will be one of my priorities and also going into the future as well.
"That’s how it started last year and the year before, Dale came in as 18th man and ended up playing a big part in what we did. It’s great to have him around."
Trbojevic, who was used a starting prop by Brad Fittler in the Origin I win in Townsville, will be out for at least a fortnight, according to Manly coach Des Hasler.
"He loves his footy Jake and he's not happy about this."
The Blues comprehensively outplayed the Maroons in a record-breaking 50-6 triumph in the Ampol State of Origin series opener.
