Laurie Daley has delivered a selection shock with Max King to make his State of Origin debut as the NSW coach also sweats on a Payne Haas quad injury.

Daley confirmed his side for the series opener on Sunday, with Dylan Edwards retaining the fullback role ahead of James Tedesco and Mitch Moses to partner Nathan Cleary in the haves.

Brian To'o and Zac Lomax have been named on the wings after Jacob Kiraz was ruled out on Sunday, set to miss at least a month with a calf injury.

Latrell Mitchell and Stephen Crichton will play centres, meaning Manly superstar Tom Trbojevic has also become a high-profile selection casualty.

Crichton will enter camp with small concern over a groin niggle, but selectors have gone with Campbell Graham as 18th man back up rather than Trbojevic.

Penrith's Isaah Yeo will take over as captain, with incumbent skipper Jake Trbojevic's concussion ending his chances of keeping his spot at prop.

But all eyes in the Blues camp this week are likely to be on Haas, if he is even cleared to fly to NSW on Monday.

The Brisbane front-rower picked up an issue in Brisbane's loss to St George Illawarra on Sunday, before the injury grew worse later in the game.

He will require scans on Monday morning, after which a decision will be made on whether he flies down to join the Blues' camp in a bid to be fit for the May 28 opener.

Haas had been carrying a back issue in recent weeks and required treatment in Sydney this month, before suffering the quad problem.

His latest setback came after a nightmare weekend for the Blues' forward stocks, with Jake Trbojevic's concussion following Jacob Saifiti's own calf injury.

The Newcastle prop had been favoured to win a bench spot, but that will now go to King with the in-form 28-year-old named in the No.17 jersey.

NSW also have Stefano Utoikamanu on stand-by as 19th man, opting against going for Terrell May despite the Wests Tigers front-rower being among the NRL's best props this year.

Meanwhile, it is the selection of Moses over Jarome Luai as Blues No.6 that looms as one of the most interesting factors head into Origin I.

Moses and Luai led the Blues to an historic series win in Brisbane last year, helping overturn a 1-0 series deficit after defeat at home.

But Cleary's return from a hamstring injury that ruled him out of last year's series has always meant the duo were realistically fighting over one spot.

Moses was close to NSW's best player in last year's comeback, while Luai held the advantage of being Cleary's long-time premiership-winning partner at Penrith.

Daley's decision will bring into question how Moses and Cleary will combine, having never played together before.

Both are also dominant halves at their club, stationed on the right-hand side of the field as right-foot kickers.

Moses has not played five-eighth regularly since his days at Wests Tigers, having been the chief conductor since his arrival at Parramatta in early 2017.
