Former UFC heavyweight champion Junior Dos Santos is preparing for his debut in the sport of boxing.

That debut will be easy, as he faces highly experienced heavyweight veteran Kubrat Pulev - in the main event of Triller's upcoming event on February 26, in Houston Texas.

Dos Santos vs. Pulev will take place in Triller's Triad Combat’s triangular ring.

The rules combine boxing with a limited amount of MMA moves - but takedowns, submissions, elbows and kicks are not allowed.

Dos Santos was stopped in his last four fights with the UFC.

But, he's up against a very dangerous opponent in Pulev (28-2, 14 KOs) - who suffered his two career defeats to world-class champions Anthony Joshua and Wladimir Klitschko.

Back in November, Pulev made his debut in Triller - under their Triad Combat rules - and blew away former UFC heavyweight champion Frank Mir in the first round. 

Dos Santos is not discouraged - explaining that styles, and rules, make fights.

“It’s a great opportunity. I’ve done some self-reflecting and I really miss fighting.” Junior told Ag Fight. “Living this period of preparation again is very exciting. I’m very motivated. Pulev is very experienced. He has fought big names in boxing, a really tough guy. He’s the kind of challenge that’ll get anyone going. I’m not going out there do a pointless fight with no career aspirations. My goal at 37 years of age is to accomplish great things. Greater than what I’ve already accomplished.

“I think the rules will help me make a perfect transition into boxing. If there ever was an opportunity for me to test myself in boxing, that’s it. This is the time. The promotion is giving boxing guys a chance do a little MMA and MMA guys to do a little boxing. It’s the perfect mix.

“I think the rules favor me when it comes to grappling. But I’m not there to grapple, you know that. I’m there to box. I want to let my hands fly, that’s what I do best. Always looking for the knockout.”
