Croatian standout Roberto Soldic, who captured gold at both welterweight and middleweight in Polish promotion KSW, is now a ONE Championship fighter.

KSW officials confirmed the 27-year old’s exit on Monday, after Soldic announced he had signed with ONE during the latest episode of The MMA Hour.

The distinction between martial arts and mixed martial arts — ONE Championship offers both MMA, and single discipline competition — appears to have been given ONE the edge over other potential suitors.

“I chose ONE because it’s the biggest martial arts promotion in the world,” Soldic (20-3) told the show. “They give me [an] opportunity to take all the belts: kickboxing world champion, Muay Thai world champion, MMA world champion, also boxing world champion. So this makes me something new. I want to create something for my people, for my own legacy. So I chose ONE for sure.”

Solidic began competing for KSW in 2017, winning the promotion’s welterweight championship in his debut. He would lose the belt in his very next fight, to current UFC star Dricus Du Plessis. An immediate rematch saw Soldic reclaim gold; he would defeat Mamed Khalidov this past December to add a second title at middleweight to his collection.

No debut date or opponent has been announced for Roberto Soldic in ONE Championship as of yet.
