Roberto Soldić Signs With UFC, Booked to Debut vs. Khaos Williams at UFC 332

The former two-division KSW champion joins the UFC as a knockout-focused welterweight and will be placed into a ready-made test that could alter matchmakers’ plans for 170 pounds.

Overview

  • The UFC confirmed Saturday that Soldić has signed a multi-fight deal and added him to its active welterweight roster, and the promotion has scheduled his octagon debut for October 3, 2026 at UFC 332 in Salt Lake City.
  • Soldić will meet Khaos Williams in his first UFC bout, a matchup the UFC listed on the UFC 332 event page that pairs two heavy-handed fighters with clear paths back toward the welterweight rankings.
  • The 31-year-old Croatian arrives with a roughly 21-4 pro MMA record, a high finish rate that includes about 18 knockout wins, and title history as a two-division champion in Europe’s KSW promotion.
  • His move follows a limited and uneven run in ONE Championship, which ended when his contract expired in August, and ends a period of free agency that had left questions about how his power-focused style will translate in the UFC.
  • Soldić’s signing reshapes matchmaking options at 170 pounds because he joins as an established external signing with marquee wins — including a knockout over Dricus du Plessis — which makes him an immediate action option for matchmakers and a potential short-term contender if he wins in October.
