Martin sent a scare through the Panthers' camp late in Sunday's dominant 46-26 semi-final win over Canterbury, when hit hard in a tackle from Viliame Kikau.
The NSW State of Origin star remained on the turf for some time, before standing up and falling to the ground again while receiving assistance from medical staff.
Martin left the field and went up the tunnel where he again appeared in significant pain, but was later seen laughing as he returned to Penrith's bench.
Afterwards, the 28-year-old insisted he had only been winded and there was no concern over his ribs.
"They're all right now. There was a bit of carry on there. It's a bit sore at the moment, but they're alright," Martin said.
"I landed on the ball, and 'Kiks' is a pretty big man and he landed on me. I was a bit winded but I'm alright now."
Martin's impact could prove crucial for the red-hot Panthers next Sunday at Suncorp Stadium.
His right edge will face a tough examination from Brisbane, with Reece Walsh having preferred that side against Canberra, tearing the Raiders apart in the first week of finals.
The Broncos could have at least one of Ezra Mam or Adam Reynolds back from hamstring injuries on that side, with stand-in No.6 Billy Walters' season ended by a knee injury.
Neither Mam nor Reynolds have played since being hurt against Melbourne in early August, with Martin ready to give either player a rough reception on return.
Mam has previously run through Penrith's right side, most notably when he scored a hat-trick in the 2023 grand final.
"That's my job in general to go after the opposition half," Martin said.
"Even if they weren't coming off a long lay-off, I'd still be going after them, so I definitely will be."
Martin may have found an unlikely co-conspirator in Panthers five-eighth Blaize Talagi, who showed off his defensive aggression in the semi-final win.
One of the smaller players on either side, Talagi made a pair of gutsy one-on-one tackles on Lachlan Galvin and Matt Burton, who both turned over possession to the relentless Panthers.
Talagi came through the juniors priding himself on his defensive intensity and said it was time to make that vigour a feature of his game again.
"Since I was young, I remember even Harold Matts (Under 16s) and that sort of thing, I was known for my defence. I want to get back to that. That's something I'll be working on," he said.
"That's always been a strength in my game. For it to finally come out, I'm happy with that."
Martin was one of two injury concerns for Penrith on Sunday, with centre Casey McLean suffering a hip-pointer injury and leaving the field early.
But the teenager also played down any concerns after the match, confident he would be fine to take on Brisbane.
"I just landed on it funny, I got up and it was a bit sore," McLean told AAP.
"I was probably just being a bit soft."
Back-up playmaker Brad Schneider also remains available, receiving only a $1000 fine for his cannonball tackle on Bulldogs forward Sitili Tupouniua.
Nathan Cleary can accept a $1000 fine for a grade-one careless high tackle on Canterbury's Connor Tracey.
