Haas is understood to have picked up a minor issue in the Broncos' 30-26 loss on Sunday, before the injury grew worse later in the game.
The front-rower is expected to be named by the Blues when they announce their 17 on Sunday night, but will require scans on Monday morning.
After that, it will be decided whether the Kangaroos international flies down to Sydney to join camp to push 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 injury comes after a nightmare weekend for the Blues' forward stocks, with Jacob Saifiti also suffering a calf injury in Newcastle's loss to Parramatta.
Incumbent captain Jake Trbojevic also had his chances of keeping his spot dashed, after he suffered a sickening concussion in Manly's loss to North Queensland.
If Haas is out, it could force the Blues to call in Terrell May as a big-minute prop.
May last week attracted headlines when he told a friend on social media he would not be picked, and recommended he chuck his NSW jersey in the bin.
The forward pack now looms as the latest big calls for returning coach Laurie Daley to make.
Mitch Moses is looming as the most likely option for the NSW No.6 jersey, with the Parramatta star firming to partner Nathan Cleary in the halves for State of Origin I.
Moses and Jarome 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 Moses and Luai 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.
The Eel's selection will bring into question how he and Cleary will combine, having never played together before.Â
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.
Daley must also decide whether to stick with Dylan Edwards or revert to James Tedesco at fullback, while there are question marks over the rest of the NSW backline.
Canterbury winger Jacob Kiraz was ruled out of contention on Sunday with his own calf injury.
Brian To'o is expected to be picked on one wing, with Zac Lomax and Tom Trbojevic the options on the other.
Latrell Mitchell and Stephen Crichton are set to be picked in the centres if fit.
AAP has also learned that Reece Robson will keep his spot as hooker, while Mitch Barnett will remain a member of the forward pack.
Daley must also decide who to make captain in Jake Trbojevic's absence.
Lock Isaah Yeo, his Penrith teammate Cleary or Bulldogs skipper Stephen Crichton are now considered options to become the Blues' next captain.
