Roberto Soldic makes UFC debut vs. Khaos Williams at UFC 332 on Oct. 4

Roberto Soldic will step into the UFC Octagon for the first time when he faces Khaos Williams in a welterweight contest at UFC 332, set for October 3 in Salt Lake City.

Soldic, 31, arrives in the UFC carrying one of the most decorated resumes in European MMA history. The Croatian knockout artist was a two-division champion in KSW before signing with ONE Championship, where he competed just three times after his debut in December 2022. With his ONE contract expiring in May, Soldic signed with the UFC and has acknowledged the extended layoff openly, describing himself as having been "semi-retired" during that stretch. He says the time away has reinvigorated him and that he now feels prepared to perform at the sport's highest level.

Standing across the Octagon will be Khaos Williams, known as "The OxFighter." The 32-year-old orthodox welterweight carries a professional record of 16 wins and 5 losses and brings serious finishing power to the matchup. Williams is six feet tall with a 77-inch reach and generates nearly five significant strikes per minute, though his striking accuracy sits at 39 percent, suggesting he prioritizes volume and pressure over precision. His UFC career statistics show no takedown activity and no submission attempts, making him essentially a pure stand-and-bang fighter who is happy to keep bouts on the feet.

Why it matters

• Soldic is one of the highest-profile European welterweights to enter the UFC in recent years, and a strong debut performance could fast-track him toward the divisional rankings.
• Williams has proven UFC experience and the kind of one-punch power capable of ending any fight quickly, raising the stakes for Soldic's first Octagon appearance.
• Both fighters prefer striking, setting up what could be an explosive, fast-paced welterweight contest in the UFC 332 main card.
