A welterweight clash between Nikolai Veretennikov and Khaos Williams has been added to UFC Vegas 117, scheduled for May 17, per reporter Marcel Dorff.
Veretennikov enters the bout holding a 2-3 record inside the UFC octagon. The Russian welterweight is looking to build momentum and secure a winning streak that would push him up the divisional ladder.

Williams, known by the nickname The OxFighter, brings considerably more UFC experience to the matchup. The 32-year-old American stands at six feet tall with a 77-inch reach and carries an overall professional record of 16-5-0, going 6-4 under the UFC banner. He is an orthodox striker who generates real volume on the feet, averaging nearly five significant strikes per minute. His approach is almost exclusively stand-and-bang, with no recorded takedown or submission activity to speak of, making his offensive intentions straightforward heading into any contest.
Why it matters
- Williams has the edge in UFC experience and overall record, but Veretennikov will be motivated to prove he belongs at this level.
- Both fighters need a win to avoid falling into must-win territory inside the welterweight division.
- Williams's high-volume striking style against a less-established opponent sets up a potentially explosive stand-up exchange.
- The result could have quiet but meaningful implications for the lower tier of the welterweight rankings picture.
