Volume Meets Accuracy
Williams lands 4.94 SLpM and absorbs 5.39. Veretennikov hits at 57% with 10 career KOs. Williams' chin has NEVER cracked in 20 pro fights. The question is whether 5.39 strikes absorbed per minute is finally where the wall comes down.
THE X-FACTOR
The Most Durable Chin in the Division Meets the Best Accuracy of the UFC Newcomers.
Khaos Williams has NEVER been knocked out in 20 pro fights. His four Performance of the Night bonuses — Morono in 27 seconds, Razak Alhassan in round 1, Baeza in round 3, Carlston Harris in May 2024 with a thudding right hand — all came with him pressing forward and letting his hands go in the pocket. The problem: 41% striking defense and 5.39 sig strikes absorbed per minute is a negative differential. He takes shots to land shots, and his two most recent losses caught up with him for it — UD to Andreas Gustafsson in June 2025 (clinch grinding, three rounds of pressure) and a D'Arce choke submission from Gabriel Bonfim in February 2025 (first time Williams has been finished in his entire career). Veretennikov comes in from the other side of the equation. The 36-year-old Ukrainian-born sambo specialist trains at Kings MMA in Orange County, and he's coming off a highlight-reel TKO of Niko Price (R1 1:42, overhand right + knee + elbow, $25K bonus) at UFC Vegas 113 in February 2026. His game is surgical — 2.69 SLpM landed at 57% accuracy and 10 career knockouts. Where Veretennikov has cracked: TKO loss to Austin Vanderford in Feb 2025 when the opponent wrestled, and a 30-27 sweep loss to Punahele Soriano in October 2025 who landed a takedown in the first minute and ground-and-pounded for three rounds. Williams doesn't wrestle (0 takedown attempts in his UFC career), which takes Veretennikov's Achilles heel off the table. This is a 15-minute kickboxing match between a volume striker with a granite chin and a sniper coming off the most dangerous KO of his year.
Truth A
Williams lands 4.94 sig strikes per minute to Veretennikov's 2.69 — almost double the volume. Eight (T)KO wins in 15 victories (53% knockout rate), 0.76 knockdowns per fight, four Performance of the Night bonuses, and NEVER been knocked out in 20 pro fights. He comes in off two straight losses but zero by KO — both came in areas he doesn't control (Gustafsson's clinch grinding, Bonfim's BJJ). On the feet with space to operate, his track record is brutal.
Truth B
Williams' striking defense is only 41% and he absorbs 5.39 sig strikes per minute — more than he lands. Veretennikov connects on 57% of strikes thrown, lower volume but a much sharper trigger, with 10 career knockouts including the demolition of Niko Price in Feb 2026 (overhand + knee + elbow at 1:42 of R1, $25K bonus). Kings MMA sambo doesn't show up against a guy who doesn't shoot, which takes Veretennikov's biggest weakness off the table. This is exactly the matchup where heavy accuracy meets porous defense.
Tale of the Tape
Veretennikov 4 years older. At welterweight, age shows up in R3 when the cardio tightens.
Veretennikov 1 inch taller. Marginal.
Williams 3 inches LONGER. Real jab/range edge in a striking match.
Same stance, no asymmetry.

Current Form
Nikolay Veretennikov
$25K Performance Bonus. First UFC finish. Price pinned against the cage, surgical sequence.
TKO R1 (1:42, overhand + knee + elbow)Soriano landed a takedown in the first minute and ground-and-pounded for three rounds. Veretennikov could not create space.
UD (30-27, 30-27, 30-27)Narrow split-decision win over an Argentine prospect.
SDUFC debut. Vanderford wrestled, took top control, ground-and-pounded until the ref stepped in.
TKO R2 (4:13)Last fight before earning the UFC contract.
UDVeretennikov hit the UFC in February 2025 and the start was rough — he lost to Austin Vanderford by TKO R2 when the opponent wrestled, scratched out a split decision over Francisco Prado in July 2025, then got dominated by Soriano (UD 30-27 sweep) in October 2025 who landed a takedown inside the first minute and stayed on top all three rounds. The reset came in February 2026 against Niko Price at UFC Vegas 113 — $25K Performance Bonus for a TKO at 1:42 of R1. Overhand right landed first, then a knee and an elbow with Price stuck against the cage. First UFC stoppage of his career and the best moment of his UFC run so far. Sambo base, trains at Kings MMA in Orange County under Rafael Cordeiro. Age is real (36 — cardio reserve raises some flags), but the trigger is calibrated.
Khaos Williams
Swedish UFC debutant. Clinch and takedowns in R2 — Williams could not find striking space.
UDFirst finish loss of Williams' 20-fight career. Bonfim's BJJ broke the seal.
Sub R2 (D'Arce choke, 4:58)Performance of the Night. Thudding right hand and Harris was out.
KO R1 (1:30, right hand)Tight split decision after three even rounds.
SDSplit decision to Brown — best-ranked opponent of Williams' career at the time.
SDWilliams is in rough shape on paper — coming off TWO straight losses and an 11-month layoff since the Gustafsson UD in June 2025, returning to action here. The first loss was the D'Arce submission from Gabriel Bonfim in February 2025 — the FIRST time Williams has been finished in his entire career (20 pro fights without a KO loss, and through Bonfim no submission loss either). The second was a unanimous decision to Gustafsson at UFC 316 in Newark — the Swedish newcomer wrestled, clinched, and grinded Williams against the cage for three rounds. Before that, Williams was on a KO of Carlston Harris in May 2024 (Performance Bonus, a thudding right hand in R1), and a split decision over Rolando Bedoya. The dilemma: Williams' best version requires space to throw heavy. His last two opponents simply REFUSED to trade with him. Veretennikov WILL trade — this is the matchup where the prime version of Williams shows up.
Level of Competition
No common opponents between Veretennikov and Williams. Calibre-wise they line up — both have been swimming in the unranked tier of welterweight. Veretennikov has 5 UFC fights at 2W-3L (Vanderford L, Prado W, Soriano L, Price W, with the immediate pre-UFC Barlow loss). Williams sits at 6W-4L in 10 UFC fights with Performance bonuses over Morono, Razak Alhassan, Baeza, and Harris, and two decisive losses (SD to Randy Brown in 2022, UD to Gustafsson in 2025). Worth noting: Williams faced Randy Brown in 2022, who would later become a top-15 welterweight — Veretennikov has not faced a top-15 opponent yet. Williams' ceiling of opponent quality historically sits higher.

Win & Loss Distribution
Wins
KO/TKO
Submission
Decision
Both finishing rates skew heavily to the knockout. Veretennikov 71% of wins by KO/TKO (10 of 14), Williams 53% (8 of 15). Veretennikov is the bigger career finisher, but most of those KOs came pre-UFC — only one stoppage in the promotion so far (the Price TKO in Feb 2026). Williams has four Performance of the Night bonuses inside the UFC and a wider distribution — six career decisions on the books. The read: if this goes the distance, Williams has more decision experience to lean on; if it ends early, both have the power to make it happen.
Losses
KO/TKO
Submission
Decision
The loss column tells the real story. Williams has NEVER been knocked out in 20 pro fights (zero KO losses), was only finished once in his career (Bonfim D'Arce in Feb 2025 — first finish ever), and everything else he loses, he loses by decision (four of five). It's a granite chin nobody has cracked. Veretennikov has 2 KO losses (29% of losses), including the TKO to Vanderford in Feb 2025, and 57% of his losses come by decision (four of seven) — usually in rounds where the opponent wrestled. The pattern: Williams loses to wrestling, clinch, and grappling, NOT to striking. Veretennikov loses to wrestling AND occasionally to opponents who hit hard first. Important caveat: Williams' chin has never been tested against a 57% accuracy sniper, and Veretennikov's chin has never been tested against the volume that's about to come at him.

Chin / Durability
+3 Williams
Williams has NEVER been knocked out in 20 pro fights. Veretennikov has 2 KO losses including the Vanderford TKO in Feb 2025.
Williams owns striking volume and the more durable chin. Veretennikov owns far better accuracy, sambo base he won't use against a guy who doesn't shoot, and gives up 3 inches of reach. The matchup boils down to one question: does Veretennikov's 57% accuracy crack Williams' granite chin for the first time in 20 fights, or does Williams stack volume and bank the cards?
Final Prediction
The Thesis
The thesis: Williams wins because, first, he has NEVER been knocked out in 20 pro fights (zero KO losses, per UFC.com profile and Verdict MMA breakdown) — a granite chin that takes him to the 15-minute mark.
The thesis: Williams wins because, first, he has NEVER been knocked out in 20 pro fights (zero KO losses, per UFC.com profile and Verdict MMA breakdown) — a granite chin that takes him to the 15-minute mark.
Second, he lands 4.94 SLpM against Veretennikov's 2.69 — almost double the raw volume, and in close cards volume beats accuracy when there's no wrestling to balance it.
Third, his last two losses came in areas Veretennikov DOESN'T attack — Bonfim's BJJ and Gustafsson's clinch — and the Ukrainian is a stand-up fighter who walks in to trade. Path: Williams works his jab from the 3-inch reach edge, controls distance, banks volume at his pace, steps out before Veretennikov's overhand, and closes 29-28 cards in rounds 2 and 3. Falls apart if Veretennikov plants his feet first and lands the overhand-knee-elbow combination the same way he did against Niko Price in Feb 2026.
Conviction
Conviction 6 (not 7) because three dimensions favor Williams (chin, volume, gameplan compatibility), but (1) Veretennikov's 57% accuracy is genuinely high — the best Williams has ever faced — and clean shots land with disproportionate weight in a striker-vs-striker matchup; (2) Williams is coming off 11 months out and a two-fight skid, ring rust + dented confidence are real; (3) Williams' 41% striking defense is a literal open door for the big shot, and Veretennikov is in KO form coming off the Price TKO. The / line reflects this proximity well — it's the kind of fight where the underdog has real value as the contrarian play.
What Breaks This Pick
- 01
Veretennikov lands the overhand cross in the first two rounds and cracks Williams' chin for the first time
- 02
11 months of ring rust kills Williams' cardio and he gives away the entire R3
- 03
Veretennikov surprises with sambo in the clinch and drags Williams down the way Soriano did to him in Oct 2025 (unlikely but possible)
- 04
Williams walks in without the jab and eats counters for 15 straight minutes
Underdog Path
Veretennikov has a real, clean path. Plant the feet in the center of the cage, let Williams come in first (Williams is volume + power = he walks in with his hands going), eat one or two jabs on the way in, and land the overhand right the same way he caught Niko Price in Feb 2026 when Price also walked in. Follow with a knee as Williams falls forward and an elbow with him pinned against the cage. That's the literal template of the Price TKO at R1 1:42. Plan B (decision): if Williams survives the early counter, Veretennikov works a measured jab, leans on the 57% accuracy, lands heavier individual shots at key moments, and banks 2 of 3 rounds on tight 29-28 cards even with lower volume — accuracy and clear damage covering the gap.
Required Conditions
- Set the feet in the center, don't retreat (Williams punishes backward movement)
- Land 1-2 clean connections per round even while absorbing volume
- Avoid the clinch (where Gustafsson trapped Williams — but also where Williams smothers)
- Cardio holds over 15 minutes of high-intensity striking at 36 years old
— Precedent: The Feb 2026 TKO of Niko Price (R1 1:42, overhand + knee + elbow) is the cleanest recent precedent. Price was also a pressure striker, decent chin, and Veretennikov read the walk-in and timed the counter. Williams walks in even more than Price did (volume 4.94 vs Price's historic 3.71), and his chin is demonstrably tougher than Price's was — but the KO template exists. A less exact precedent is Williams' own KO of Razak Alhassan in 2020, when Williams beat an explosive striker to the punch — proof that Williams also wins those early-trigger exchanges when he sets the trap first.
Verdict
Winner
Khaos Williams
Method
Unanimous Decision
Most Likely
- 01
Winner
Khaos Williams
Real probability estimated at 52%, implied is 55%. Marginal edge but it's there. The chin (NEVER KO'd in 20 fights) is the discount that justifies the play even with the porous defense. Medium conviction — this fight could go either way.
- 02
Winner (contrarian)
Nikolay Veretennikov
45% real estimate against the 49% implies — marginal value. The upset path is a TKO repeating the Niko Price template (overhand right exploiting Williams' 41% striking defense). For the underdog play in a 50/50 fight, pays well.
- 03
Total Rounds
Over 1.5 rounds
Both men carry KO power, but Williams has NEVER been knocked out in 20 fights and most of Veretennikov's career KOs came pre-UFC — only one finish in 5 UFC bouts. UD or late TKO is more likely than an R1 finish.
- 04
Method
Fight ends by Decision
Williams has NEVER been knocked out, both fighters have high SApM but Williams absorbs and stays standing, and neither pushes wrestling for the sub. Decision is the likeliest outcome regardless of who wins. The implied is 45%, edge over a 60% real estimate.
Most Likely Outcome
Fight ends by Decision
Safest play on the matchup. Williams has NEVER been knocked out in 20 pro fights and has only been finished once (BJJ, not striking — against Bonfim, and Veretennikov isn't a grappler). Veretennikov has only one finish in 5 UFC fights (the Price TKO). The paths to a stoppage before the final bell are limited on both sides — Decision works no matter who gets the W.
Stats That Matter

The Trap
The Trap: Veretennikov by Specific KO
The market will pay heavy on 'Veretennikov by KO/TKO' based on the highlight-reel TKO of Niko Price in Feb 2026 (R1 1:42, $25K bonus) and 10 career knockouts. But Williams has NEVER been knocked out in 20 pro fights — he's traded with Randy Brown (top 15), Carlston Harris (a finisher himself), Miguel Baeza, and Abdul Razak Alhassan (heavy puncher) without going down. Betting Veretennikov by specific KO means betting that Williams' chin breaks for the FIRST TIME in his career against a 36-year-old throwing 2.69 SLpM. Possible, but it's a bet on a first-ever event. Smarter play: simple ML if you want the dog, or combine with the over-rounds prop.
