Panthers young gun Casey McLean will be sent for scans after he suffered an ankle injury in his side's dominant win over Wests Tigers on Sunday afternoon.
The outside back landed awkwardly after catching a kick early in the second half and while he initially attempted to play on, left the field soon after.
Penrith don't believe the injury is serious and McLean spent much of the second half riding an exercise back. While scans will confirm the severity, even a minor injury could impact his State of Origin chances if he is unable to train fully with the Blues in camp.
McLean starred when injected off the bench in Game One at Accor Stadium and looked set to retain his place on the six-man interchange before Sunday's injury.
"He's going to get a scan," Panthers coach Ivan Cleary said. "I'm not sure how that works with camp but he'll get it scanned.
"I think it's not too bad. His syndesmosis is apparently intact, that's the biggest danger. I think he'll be alright but I'm not going to speculate."
NSW coach Laurie Daley will name his team for Game Two on Monday night following the conclusion of Canterbury's King's Birthday clash with the Eels.
Eels halfback Mitch Moses won't take part in that match and is expected to be given a fitness test on his injured hamstring on Monday as he pushes for a return to the Blues squad after being a late withdrawal in Game One.

Cobbo, Katoa, Campbell impress
Selwyn Cobbo starred for the Dolphins, while team-mate Isaiya Katoa and Titans playmaker Jayden Campbell put themselves in contention for Origin call-ups.
However, Ezra Mam and Reece Walsh had mixed nights for the Broncos, who were beaten 28-23 by the Titans as last year's premiers slumped to a fifth consecutive loss.
Maroons coach Billy Slater announced on Monday that Walsh had been recalled for Game Two at the MCG while Mam was overlooked after he was unused reserve in the series opener.

Sea Eagles unscathed (NSW)
Manly duo Tolu Koula and Haumole Olakau'atu have taken a big step towards retaining their spots in the NSW Origin team after impressing in their side's victory over the Rabbitohs.
Koula made his debut in the series opener at Accor Stadium before he was knocked out by a Kalyn Ponga shoulder charge midway through the second half.
The outside back received clearance from an independent doctor to take his place in the Sea Eagles' side on Thursday night and got through the night unscathed.
Olakau'atu starred for Manly in the 28-14 win over South Sydney, running for 266 metres and terrorising the Rabbitohs defence.

The edge forward left the field in the final minute of the match but Sea Eagles coach Kieran Foran said it was simply cramping.
"It was just cramps," Foran said post-game. "He's had a big month, Haumole. His game tonight was outstanding.
"We didn't want to risk him there with a couple of minutes to go so got him off the field."
Bunnies skipper Cameron Murray also got through the game as he looks to retain his place in the Blues side.

Reece Walsh (Queensland)
The Kangaroos fullback appeared frustrated for much of the Broncos match against the Titans and was badly beaten by a runaway Phil Sami on the way to his 70m try just before halftime. He was seen hobbling at stages of the match and it was reported that Walsh was hampered by a cork. Despite an indifferent night, he still managed to run 254m from 28 carries of the ball, produced a line-break and some strong defensive efforts.
Payne Haas (NSW)
The Broncos prop got through 80 minutes in his second game back from injury and is expected to be first frontrower picked by Blues coach Laurie Daley. Haas ran 187m from 18 carries, including 86 post contact metres, and produced four tackles breaks and two offloads.
Selwyn Cobbo (Queensland)
The Dolphins flyer had arguably his best game for the club, scoring two tries and running 321m with the ball, while making a line break and eight tackle breaks. Cobbo is playing with confidence and is certain to retain his spot on the wing for Queensland.
Classic Cobbo
Isaiya Katoa (NSW)
The Dolphins halfback was NSW coach Laurie Daley's first choice to join the Blues squad after Mitchell Moses suffered a training injury in camp for Origin I but was himself battling a knee problem so Matt Burton got the call up. Katoa played with his knee heavily strapped in the 40-14 defeat of the Cowboys but was unaffected as he guided the Dolphins to their fifth consecutive win. If Daley decides that Moses is underdone or not fit, Katoa could win his first Origin jersey.
Isaiya Katoa Try
Kalyn Ponga (Queensland)
Knights skipper and Queensland fullback Kalyn Ponga missed the post-match press conference after Newcastle's loss to the Strom due to a neck issue that he sustained in the second half.
"He's real sore, so he's getting some work on it now," Knights coach Holbrook said.
"I think it might just be one of those burners, but then they sort of tighten up and it's pretty stiff at the moment, so hopefully that's all it is."
Ponga looked in major discomfort early in the first half when he went down clutching at his left shoulder after being fended heavily by Jahrome Hughes on his run to the tryline, but he rejoined his team and played on.
Mitchell Moses (NSW)
The Blues five-eighth is racing the clock to be fit for Game Two after injuring his hamstring just two days before the series opener. Coach Laurie Daley has suggested the playmaker will come straight back into the side if healthy.
Moses will miss Parramatta's clash with the Bulldogs on Monday afternoon and will need to be able to train from Wednesday if he is to take his place in the NSW team.
Ethan Strange will retain the No.6 jumper if Moses falls short in his recovery from injury with Isaiya Katoa the man most likely to be added to the bench.
Ethan Strange Try
Pat Carrigan (Queensland)
Queensland have been dealt a blow with veteran forward Pat Carrigan undergoing surgery for an ankle injury suffered in last week's loss to the Dragons.
The lock is facing six weeks on the sidelines, ruling him out of Game Two and making it highly unlikely he will be available for the third match of the series.
Brisbane and Queensland teammate Gehamat Shibasaki will also miss the match at the MCG after suffering a Grade 2 MCL injury that will keep him out of action for 5-6 weeks.
Stephen Crichton (NSW)
The Bulldogs centre reaggravated a shoulder injury in last week's loss to the Tigers. Crichton has battled the AC-joint issue since his side's Good Friday loss to the Rabbitohs.
The centre nursed the injury through the Blues lead-in to Game One and was on restricted duties early in the camp before taking his place at Accor Stadium.
Crichton has also been restricted at training this week but Bulldogs coach Cameron Ciraldo is hopeful he will take his place in the team on Monday afternoon.
"A bit more hopeful on him," Ciraldo told reporters on Thursday.
"Our team's really unknown at this stage, we're probably very lucky we're playing on Monday."
The news is less positive for Bulldogs teammate Jacob Kiraz, who emerged as an outside contender for a Blues spot this week.
The outside back injured his calf in the warm-up last week before bravely playing through the pain. Ciraldo rated him a "50-50" chance to play against the Eels.
