Tim Tszyu stood with a pair of title belts draped over his arms, his face bereft of bruises and instead bearing a humble smile. Occasionally splitting the cheers and laughter was Kostya's voice.
Tszyu's manager Glen Jennings touched each of his cheeks and his nose, and the former undisputed world champion on the other end of the video call in Russia simply smiled and said "no touch".
Because his son (17-0) came out of another bout unscathed, claiming the WBO Global and IBF Australasian super welterweight championships in a 114-second demolition of Kiwi Bowyn Morgan (21-2).
Tszyu had been searching for that stinging shot that sends opponents "into a dazzle", and he found it twice to floor Morgan in front of 11,820 at Western Sydney Stadium on Wednesday night.
But Kostya's highlight? Not the right hand which sent Morgan to the canvas seconds after he staggered to his feet. It was the fact his boy came through effectively untouched, because Jennings says "that's all he says to Tim".
"Every time before the fight, he sends me a message every time, 'just don't get hit'. Thanks for your tips, mate," Tszyu laughed.
Now negotiations begin for Tszyu's shot at the WBO title, which looms likely with Patrick Teixeira and No. 1 ranked challenger Brian Castano running out of time to secure a bout by a January 6 deadline.
While world-ranked Morgan failed to land a blow of any substance, a realistic Jennings says "we know some of these guys Tim is going to face in the future are going to hit him" - but the Tszyu camp are adamant their man is ready.
"I'd look at the Charlos, I'd look at the Jarrett Hurds and the Julian Williams'. I'd think 'these are big men', and back then Tim was still a rookie, young lad," Jennings said.
"Look at him today, he's ready, we're ready. There's no one that worries us now. Timmy is ranked in the top 10 in every association, including Ring magazine, that's when you know you've arrived.
"The exciting thing about his division is if he wins that world title, one fight after that could be unification. [Jermell] Charlo has got the lot [WBC, WBA, and IBF titles]. The long vision for us, if he can knock over Castano or Teixeira, we'll be knocking on a certain door.
"We won't die waiting. I have absolutely no problem with going after the big guys now. He's ready, he has done his apprenticeship, he has arrived.
"The world is watching. What you've seen is an evolution, and now the world knows Tim Tszyu is ready for the world stage."
Jennings and Tszyu's promoter Matt Rose are targeting a world title bout in Sydney - potentially at the site of this week's trans-Tasman destruction - in March or April of 2021.
If the title holder tells Tszyu he wants to fight in the United States or anywhere else, the face of Australian boxing says "I'll fly straight there".
"If we're doing shows like this, why wouldn't they [come to Australia]? You can fight in front of no one in America or you can fight here in front of a big crowd," Tszyu said.
"That's more for my fans, for them to experience it. For me, of course I want it to be here, to fight in front of my fans. Just give me a ring, that's all I need.
"I'm getting more and more mature. I just turned 26, I've got another three or four years until I reach my peak. That's why I want to have the best experience, to be fighting the best fighters right now.
"I'm a very goal-driven person. The goal keeps climbing up unfortunately, but that's what makes me keep being so obsessed with my training. That's what allows me to get up each morning.
"I had a tough opponent in front of me, and I got him with the right shot. I worked a lot on power this camp, as you can see my physical shape is ... I'm getting bigger and stronger. I'm working on individual punches. It paid off.
"This was a world title eliminator for me, so there are only two names on the list right now. That's Castano and Teixeira."
