Werdum and dos Santos Are Going Back to War — But Nobody's Striking This Time

Two former UFC heavyweight champions have fought each other twice in the octagon. Now they're meeting in pure grappling. Fabricio Werdum vs Junior dos Santos at Kings Championship on August 8 in Florianopolis, Brazil — their third encounter, and the first one that won't involve striking, judges who don't understand jiu-jitsu, or some version of cardio collapse at the championship level.

This is the kind of story that sounds trivial until you actually think about it for more than seven seconds.

Werdum's grappling pedigree is unambiguous. Multiple-time ADCC champion, IBJJF world champion, the guy who spent fifteen years inside the UFC octagon using leg locks from positions that shouldn't exist and heel-hook sequences that opponents had never seen defended. His striking is respectable but it was always the setup. The real work happened when he got you to the mat and got creative. He's been outside the UFC long enough now that stepping into a pure-grappling ruleset is probably closer to his actual skill level than the heavyweight striking game ever was.

Dos Santos is a different animal entirely. His wrestling base exists — the sprawl was legendary, the takedown defense was part of his game against everyone — but his last relevant MMA fight was a bare-knuckle bout against Werdum in 2023, which he won by decision. Before that, you're looking at UFC history: knockout losses to Stipe Cormier (twice), a knockout loss to Fabricio Werdum in 2010, and eventually a slide into financial necessity punctuated by whatever fights pay the bills in third-tier promotions. His recent grappling record shows a loss to Robelis Despaigne and a knockout win over Alan Belcher. Neither suggests he's been grinding competitive jiu-jitsu at an elite-level academy.

So you have Werdum, a legitimate heavyweight grappler with ADCC credentials, meeting a former UFC heavyweight whose wrestling was always about staying on his feet and keeping punching distance. One guy is meeting grappling on home turf. The other is meeting grappling because someone's paying him enough to risk it.

The story is obvious: two heavyweights, separated by 17 years since they first fought in the UFC (June 2009, dos Santos by knockout), meeting on pure-grappling terrain with completely different skill architectures. Werdum hasn't competed since their 2023 bare-knuckle encounter. Dos Santos has been in and out of fighting through a succession of declining-competition promotions.

But the subtext is where the snark actually lives.

The Skill Gap

If you were analyzing this fight on technical merit, the answer is immediate: Werdum should dominate. He trained at high levels of jiu-jitsu for two decades. He learned to fight heavyweights in the UFC, which means he learned to control large bodies on the mat. He's won ADCC. He's been submitted maybe three times total in his entire professional career, and never at heavyweight in a pure-grappling context. Dos Santos has been struck in the face by professional strikers so many times that his grappling foundation — such as it is — has atrophied from disuse.

What you'd watch for: Werdum hunting leg locks immediately. He's been leg-locking since before it was trendy in the UFC. He pressures from top, threatens heel hooks from 50/50, forces dos Santos to defend positions he hasn't had to defend seriously in a decade. Dos Santos stays upright and avoids the grip fight. He sprawls. If he goes to the mat, he escapes or gets trapped in leg-lock exchanges where Werdum actually lives.

If dos Santos gets taken down, it's over in three minutes. Werdum's guard passing, his top pressure, his leg-lock entries — all professional-level grappling. Dos Santos' wrestling is MMA wrestling. Different sport, different rules, different endgame.

If dos Santos stays on his feet for eight minutes of a grappling match, it becomes a game of who ages worse. And dos Santos is 42. Werdum is 46. You're not banking on either one's conditioning.

The skill gap should be enormous. The actual result is probably just as obvious.

Why This Match Exists at All

Here's what matters more than the actual matchup: the fact that grappling promotions can now pay UFC heavyweights enough to motivate them to come back. They couldn't do this five years ago. ADCC was breaking into mainstream consciousness, sure, but heavyweight grappling wasn't a standalone career for guys in their 40s whose prime was measured in decades.

Werdum's willingness to accept this fight signals he still believes his grappling is the answer. Or he needs the purse. Could be either. Stepping back into competition at 46, in a pure-grappling ruleset, after years out of the game — that's either confidence or necessity.

Dos Santos accepting signals something else. He's been in a slow decline through MMA, bare-knuckle boxing, and whatever regional promotions still book him. Now he's agreeing to a pure-grappling match against someone he's already beaten twice in sports that favor him. That's either overconfidence or a final cash grab before the market stops calling. Kings Championship is paying him to show up. He's showing up.

What This Says About Grappling's Current Market

Grappling is cannibalizing MMA's narrative now. The guys who were too good at grappling to ignore in the octagon are now in a position where they can skip the striking entirely and get paid to do the thing they were actually best at. Werdum's been circling back to grappling throughout his career. This is just the obvious punctuation mark: a full circle back to his original sport, against a guy he beat and was beaten by in different rulesets, now in the one ruleset where his dominance is actually guaranteed.

The fact that both guys agreed to this fight in front of a worldwide grappling audience says the sport is legitimate enough now to host a real trilogy with real stakes, even if one of the combatants is clearly outmatched in the specific discipline. Grappling promotions have the budget now. Grappling fans have the viewership. The athletes have incentive.

Werdum's ADCC credentials and Strikeforce/UFC heavyweight résumé make him a draw. Dos Santos' UFC notoriety and two previous victories over Werdum make the narrative complete. Kings Championship is selling the rematch trilogy, not the grappling match. The grappling is almost secondary to the novelty.

Historical Precedent

This isn't the first time a UFC heavyweight transitioned to pure grappling. Cain Velasquez dabbled in professional wrestling, which is a different thing entirely but it's the same energy: a guy who was elite in one grappling context exploring another. Anderson Silva fought Jake Paul in boxing, which is the wrong direction but it's the same willingness to test yourself in a different format. The migration usually flows MMA-to-grappling, not the other way around, because grappling is more technical and has fewer escape routes.

Werdum's return to pure grappling at 46, meeting a former UFC heavyweight, is the logical endpoint of the grappling-crossover conversation. These are guys at the end of their financial rope, trying to monetize whatever competitive advantage they still have. Werdum still has his jiu-jitsu. Dos Santos still has his name.

The Real Story

Expect Werdum to win fast. Expect dos Santos to stay standing as long as possible. Expect the grappling community to watch a UFC legend prove that grappling, not striking, was always his best work.

But the actual story isn't the match result. It's that grappling is now big enough that it can host this exact match — two heavyweights, one legitimate, one desperate, meeting 17 years after they first fought, in a sport that's figured out how to pay them both. That's market validation. That's grappling's moment saying: you don't need the UFC octagon anymore. You come to us now.

August 8. Florianopolis. Werdum vs dos Santos. Part three. The trilogy nobody asked for, everyone will watch, and nobody will be surprised by the outcome. But they'll watch anyway, because grappling's finally got the production value and the purses to make it an event.

That's the real grappling story this August.
