There was a moment early in his comeback match for New Zealand against Tonga in Newcastle on Saturday night when Kalyn Ponga knew his broken arm was fully healed.
Running off his line in the eighth minute, Ponga was flattened in a front-on tackle from former Knights teammate Tyson Frizell.
Sucking in deep breaths while standing to play the ball, stinging all over, Ponga smiled.
Returning from the injury he suffered in New Zealand's 24-22 loss to Australia in the World Cup tournament-opener 23 days earlier, Ponga was happy to be back where he belongs.
There was a similar tackle by Tongan hooker Salesi Foketi 12 minutes later, which momentarily rattled the Kiwi fullback, but he again dusted himself off and played on.
Played a blinder, in fact, setting up three tries, running for almost 200 metres, and making several try-saving tackles to propel New Zealand to a 34-10 semi-final victory and a place in the World Cup final in Brisbane next Sunday night.

"It was awesome. Obviously I had a taste of it, that first game, and I've been watching from the sidelines the last couple of weeks," Ponga told reporters after the game.
"I just wanted to my job out there, obviously, and I was pretty confident I could do that, and I'm glad I did that.
"I feel fine. My body actually feels pretty good, my arm felt really good, which is good, but I'm just filthy that I got hit a couple of times... I haven't been hit like that for a while, but my body's fine."
Kalyn Ponga just shy of a miracle moment
Originally named in jersey No.21 on New Zealand's extended bench, Ponga convinced coach Stacey Jones of his fitness at training late in the week and replaced Keano Kini at fullback when Jones finalised his team 90 minutes before kick-off.
Ponga said he had a metal plate and 11 screws in his arm, having undergone surgery immediately after he suffered the injury against Australia.
He sought advice from playmaker Jahrome Hughes, who returned for Melbourne against Cronulla in a 2025 preliminary final just 22 days after fracturing his left forearm.
Sharks hooker Blayke Brailey made a similarly speedy recovery earlier this year, returning three weeks after breaking his right forearm.
"To be honest, it probably came good late," Ponga said.
"Talking to Hughesy, he trained the week before and had a lot of confidence, and I wasn't quite there yet, but I trained Tuesday and Wednesday and felt quite good.
"I think someone told me someone's come back in three weeks, I like a challenge, and that was obviously the only thing that I heard in my head – someone else did it, so I can do it...

"I didn't feel it at all out there. If anything, my lungs were hurting more than anything."
Jones said Ponga's fast-tracked return was a combination of the player's determination and "it's just where sports science is these days".
"I saw what he had in his arm – the rod, or the plate, it was covering nearly his whole arm," Jones said.
"Jahrome Hughes had a similar injury last year and he came back from it, so I think now where it's at, people can just recover from it.
"And it's also the individual. He's a tough character.
"And after the Australian game, he was so adamant that he was playing but you don't know.
"We didn't know until after our second to last training that he was going to be right, and he ticked all the boxes, so he's just a tough person." \
Ponga had three try assists, making the final pass for tries by Briton Nikora, Casey McLean and Xavier Willison, and ran 18 times for 193 metres, constantly testing Tonga's defence around the ruck and on the edges.

He also saved tries with tackles on Demitric Vaimauga, Lehi Hopoate and Siua Wong, showing no concerns about testing his left forearm under duress.
"Obviously, [he's a] freak of a player, [but] you got to see the defensive mindset he had tonight – saved a couple of tries there – and that's what I love about KP," Kiwis skipper James Fisher-Harris said.
"He's obviously a freak of nature, but I think his leadership skills are very under-rated, especially with the Knights this year, and he's been really good for us – our spine especially, and the whole squad.
"At the same time, if Keano Kini had his chance, he wouldn't have let us down as well, so we're pretty fortunate in that aspect of things."
Ponga said he had paid more attention this year to his defensive duties and responsibilities, refining his tackling technique and positional awareness.
"Given the way our finals run unfolded, and the pressure that we had to withstand, I guess, I got a lot of practice in that area," Ponga said.
"I've been watching a lot of footage and footy, and Dylan Edwards is probably the main guy that I watch in that area, and his work ethic off the ball, his positioning and everything, is probably the best in the game, so I'm trying to be a complete player, definitely."

The crowd of 29,712 at McDonald Jones Stadium was the largest Ponga had ever played in front of in Newcastle but, with so many flag-waving Tongan supporters in the stands, it felt like anything but a home game.
"It's different. I've always wanted to play in front of the Red Sea," Ponga said.
"You've seen the support they've had over the last three or four weeks... and I was looking forward to that, and for us, it was such a big occasion as well."
Though it will not ease the pain of Newcastle's 19-18 loss to the Roosters in the NRL grand final last month, Ponga has the chance to finish the finest season of his career with a World Cup victory at Suncorp Stadium.
"They're different goals, obviously, and as soon as you get into this camp, you almost forget about what's happened in the past. You're just so wired to chase what's next," he said.
You've never seen a stare down like it!
"It would be awesome and such a reward for not only this team, this group that's been together for so long, but the country as well.
"I've waited, bided my time, and I always felt like this was the right decision for me. I copped some backlash for that, but at the end of the day, it's who I am, and it's my culture.
"I'm extremely proud to be in this position, extremely proud to be playing in a World Cup next week, but there's a lot of work to be done."
