Panthers superstar Nathan Cleary is in doubt for Origin I after suffering a recurrence of his nagging hamstring injury during Friday night's match against the Bulldogs.
Cleary came from BlueBet Stadium just before half-time after calling for assistance from a Penrith trainer after chasing his own kick and spent most of the second half watching from the coach's box with ice on his leg.
Panthers coach Ivan Cleary said: "He's pretty shattered actually. It's very disappointing for him. I'm torn between his coach and his dad right now.
"We've got to get a scan and see the damage. He felt it straight away, so he knew, so that suggests it's decent."
The latest injury concern for Cleary will have Blues coach Michael Maguire on edge after he missed last weekend's match against the Rabbitohs just a week after returning from a five-week lay-off with a hamstring injury.
Cleary suffers recurrence of hamstring injury
Cleary's Origin campaign was also disrupted last year due to a hamstring injury.
"Especially that first half, I thought he was really starting to come into his own but the show goes on," Ivan Cleary said.
"It hasn't been a problem, he didn't play last week because we had a five-day turnaround and he's basically done every session for two weeks without any drama."

Cleary's deputy Brad Schneider also failed to finish his match in NSW Cup after suffering a knee injury.
A blow for Cronulla with star playmaker Nicho Hynes dropping out after Friday's captain's run due to calf tightness.
The club reported that Hynes was given every chance in a bid to take his place in the team to face Melbourne, but coaching and medical staff were of the belief the risk of further damage was too great.
"We haven't had a great deal of time to assess it but I'd suggest it's not significant though so he's a good chance [for next week]," Sharks coach Craig Fitzgibbon said post-match.
Both the Wests Tigers and Knights suffered mid-game injuries during their clash in Tamworth, with Knights five-eighth Tyson Gamble suffering a potentially serious foot injury which saw him on crutches after being ruled out at half-time.
Wests Tigers centre Starford To'a also picked up a hamstring injury on 15 minutes and back-rower John Bateman was ruled out at half-time with a pectoral problem.
"Starford is probably going to miss a couple of weeks with a hamstring and Johnny will have to have scans, a suspected strained pec, maybe a tear," Tigers coach Benji Marshall said post-match.
Knights coach Adam O'Brien said Gamble had "a break on the outside of the foot so it's not ideal, another spine member down for us".
The Warriors are facing a stint without the services of centre Roger Tuivasa-Sheck, after he suffered a hamstring injury at training in the lead up to Round 10 clash with the Roosters, who will be without Brandon Smith (calf).
The Blues and Sea Eagles were dealt a blow with Tom Trbojevic expected to be unavailable for seven weeks with a hamstring injury.
With Origin I to be played at Accor Stadium on June 5 and Origin II at the MCG on June 26, Trbojevic is set to be unavailable for the first two matches of the series and may be racing the clock for Origin III at Suncorp Stadium on July 17.
Trbojevic and winger Jason Saab were sent for scans after failing to finish Thursday night's match against the Dolphins at Suncorp Stadium.
Saab lasted just 18 minutes before landing heavily on his shoulder in attempting to score a try, while Trbojevic limped off 12 minutes from full-time.
A Sea Eagles statement said Trbojevic would be sidelined for approximately seven weeks by a hamstring injury, while Saab has an A/C joint injury and will miss several weeks.
The Broncos, meanwhile, lost hooker Billy Walters to a wrist injury early into their win over the Eels on Friday night.
Walters left the match in the 13th minute and did not return, with coach Kevin Walters revealing he could be in doubt for Magic Round.
"Billy's got a ligament problem in his wrist and he got a bang on it early in the game so he could barely pass," Walters said post-match. "I'd say he'd be in doubt for next week."
