While boxing and mixed martial arts enthusiasts around the world were focused on watching Floyd Mayweather Jr. and Conor McGregor fight this past weekend, one Regina man was preparing for his own fight in Vegas — and he's coming home with a world championship title.

Martial artist A.J. Scales, owner of Complete Martial Arts and Fitness in Regina, was competing in the International Brazilian Jiu-Jitsu Federation 2017 World Championships.

The Regina-raised member of the George Gordon First Nation won four matches to take the gold medal in his category and the coveted title of "world master."

"I won one match by submission and three by points," he told CBC Radio's Morning Edition.

"In the final match, I was going against a multiple world champion [who] has been a black belt as long as I have been training."

Scales, who started practicing the martial art of Brazilian jiu-jitsu in 1998, said back then there wasn't any real gyms to train in.

"It was still very new," said Scales.

"I started learning out of magazines. I'd go to the 7-Eleven and there was a magazine called "the grappling magazine," and they'd demonstrate moves with pictures," he said with a laugh.

Scales's long-time training partner and friend Janz Stein said that the now-world master has always been there for him. So Stein was proud of him when he heard the news about the gold-medal win.

According to Stein, from the first time they met in an old basement gym, he and Scales formed a bond that still holds today.

"He became more of a mentor for me than my actual coach was," said Stein.

"From that day on I've always considered A.J. my coach … I think it was the love of the sport and dedication and what it takes to get to the level we are at," he said.   

Stein, who is a former professional mixed martial arts athlete with an undefeated record of 3-0, said Scales was in his corner for every fight. Stein retired from professional fighting due to a dirt-bike accident that forced the amputation of his left leg below the knee.

Now a national para-athlete champion and record holder in long-jump and 100-metre dash events, Stein still turns to Scales for support.

"A.J. is always kind of there for me even though I haven't been around the gym a lot in the last [few] years. He's always there for me and for all his students," said Stein.  

For more than a decade, Scales has competed in tournaments against some of the best in the world, including UFC legend Georges St-Pierre.

After spending years travelling to Brazil to train in Brazilian jiu-jitsu, he always returned to the Queen City.

"I'm from here, my roots are here," said Scales.

"I felt that this is my home and I think I should stay here and pass on jiu-jitsu to people in Saskatchewan."
