Reinier de Ridder’s journey from ONE Championship to UFC in 2024 isn’t just a story of switching promotions—it’s a brutal spotlight on how some fight organizations might actually be setting traps rather than launching pads for rising MMA stars. The Dutch powerhouse, former two-division champion of ONE Championship, didn’t mince words when he blasted his ex-promoter for what he described as career sabotage. After dominating the Asian MMA scene, de Ridder found himself stuck in a contractual nightmare that sidelined him for an entire year. Now, fresh off a streak of three UFC finishes, including a stunning upset of Bo Nickal, he’s throwing down a clear warning for fighters: think twice before signing with ONE. This isn’t just a petty grudge match—this is about the real struggles athletes face behind the glitz of fight promos and flashy events.
The bitter reality for many MMA warriors? Contracts aren’t just ink on paper; sometimes, they’re shackles disguised as opportunities. ONE Championship, once hyped as the pinnacle of MMA in Asia, has shifted gears in recent years, pivoting heavily towards Muay Thai and kickboxing events. Its management woes and financial instability aren’t just whispers backstage—they’ve openly admitted to grappling with profitability issues. And for fighters caught in their web? It’s often a slow death of momentum, as unseen restrictions and a maze of red tape keep them benched and fighting for scraps. De Ridder stepped out of this labyrinth, risking legal battles and personal sacrifice, to breathe new life into a career that was on the chopping block.
Yet, the story doesn’t end with de Ridder. His one-time teammate Marcus “Buchecha” Almeida recently walked the same tightrope, echoing frustrations about ONE’s tight hold on its fighters. Their experiences paint a grim picture of athlete welfare and career development being an afterthought in some corners of the combat sports world. Behind the scenes, it’s a tug of war between athlete ambitions and promotion’s self-interest, often leaving fighters in the crossfire.
In a sport where every punch and takedown counts, it seems like the fights outside the cage for athlete management and sports promotion aren’t getting enough spotlight. De Ridder’s raw callout is a reminder: mixed martial arts is a battleground not just for titles, but for survival within a system that, at its worst, might just be aiming to undermine the very athletes who make it all possible.
How Reinier de Ridder’s brutal split with ONE Championship exposes athlete career risks in MMA promotions
When you’re a world-class mixed martial arts titan like Reinier de Ridder, who obliterated the 205- and 225-pound divisions in ONE Championship, you’d expect the organization to nurture your career like a prized asset. Instead, what he got was more like a slow choke hold. After claiming the belts with unforgettable wins over Aung La N Sang, De Ridder’s trajectory came to a screeching halt thanks to what insiders call “contractual limbo.”
This limbo wasn’t some minor inconvenience. De Ridder sat on the sidelines for most of 2023, unable to fight or chase new opponents while under ONE’s thumb. Two back-to-back losses against Anatoly Malykhin added fuel to the fire, but the real kicker was the promotion’s refusal to let him fight elsewhere or negotiate exit terms. This shenanigan is more common than fans think and points to a larger problem with athlete management in the fight industry.
The harsh truth?
- Contracts with ONE Championship can be restrictive, almost imprisoning talent.
- Fighters face limited freedom to move, even when the organization fails to provide fights or fair compensation.
- Career development opportunities stall, risking years of prime combat days.
In MMA, where form, fitness, and momentum are everything, a forced hiatus can feel like a death sentence for a fighter’s trajectory. Reinier found himself grinding against an invisible opponent—bureaucratic inefficiency and poor athlete welfare dictating his fate more than his own skill or heart ever could.
This isn’t a new narrative. You only need to glance at contract woes in the broader MMA scene to see how fighter rights get trampled in the name of promotion profits. ONE, which once promised to be Asia’s MMA crown jewel, has lately seemed more focused on promoting kickboxing or Muay Thai bouts, which might explain its strategic pivot yet raises questions about how committed it still is to mixed martial arts and its athletes.
See the rough patch this table below paints for artists stuck in promotional purgatory:
| Issue | Impact on Fighter | Example |
|---|---|---|
| Contractual Limbo | Inactive fighters, lost momentum | De Ridder sidelined all 2023 |
| Restricted Fight Opportunities | Limited career growth | ONE’s refusal to release fighters |
| Promotion Shift To Other Combat Sports | Less MMA exposure | ONE focuses on Muay Thai/kickboxing |
| Legal Disputes | Financial strain, distractions | De Ridder & Palm Sports lawsuit |
Just like WHEN a striker’s jab falters in the cage, an organization fumbling with athlete management can break a fighter’s career before they land the first big punch. De Ridder’s story is that jab—sharply landing a reality check on the industry’s darker side.

Inside the UFC breakthrough: Reinier de Ridder’s rapid rise post-ONE Championship exit
One thing about Reinier de Ridder: he doesn’t do things halfway. After patiently choking on ONE Championship’s chokehold, he finally jumped ship to the UFC with the subtlety of a bull charging through a china shop. The results? Unignorable. Three finishes in a row since his UFC debut, capped by the impressive demolition of Bo Nickal, a rising star and ex-college wrestling phenom hyped to the rafters.
De Ridder’s UFC run isn’t just a lucky streak. It’s the payoff for years of grinding technique and unyielding determination—traits that get polished when you have the right camp, the right coaches, and the freedom to fight. At Kill Cliff Fight Club, where de Ridder has been putting in the work, his striking finally caught up with his grappling prowess, leaving the MMA world taking notice.
- Streak of three UFC finishes, including TKO over Bo Nickal
- Elevated striking skills developed over a decade, finally unleashed on a global stage
- Strong support network and training environment fueling continuous improvement
- Rank ascension from unranked to No. 13 and climbing
His upcoming headliner against Robert Whittaker, former UFC middleweight champ, is a make-or-break moment that will surely determine whether De Ridder is just a UFC curiosity or a legitimate title contender. Expect fireworks because Whittaker’s style—slick, technical, and seasoned—is a perfect storm against de Ridder’s iron-willed pressure.
De Ridder acknowledges the leap in competition but remains humble: “This fight is another step, not the final stop. But yeah, beating a guy like Whittaker would be a statement no one can ignore.”
| Key Metrics | ONE Championship | UFC |
|---|---|---|
| Number of Fights since debut | Approximately 15 (2019-2023) | 3 (2024 – Present) |
| Wins | Majority, including two-title reigns | 3 (all finishes) |
| Fighting Style Growth | Primarily grappling & control-based | Expanded striking and well-rounded MMA |
| Rank in Division | Top 5 (ONE’s middle & light heavyweight) | No. 13 and climbing (UFC middleweight) |
It’s safe to say the freedom to pursue fights without bureaucratic chains has been De Ridder’s fuel. With a fresh contract and a goal that includes UFC gold, his path is finally his own to carve—no more corporate roadblocks, just a fighter’s pure ambition unleashed.
ONE Championship’s strategic shift: How moving from MMA to Muay Thai and kickboxing affects athlete welfare
Since its early days as Asia’s MMA powerhouse, ONE Championship has taken an unexpected detour, pivoting aggressively towards Muay Thai and kickboxing. This isn’t just a stylistic shift—it’s a radical rebranding that has serious implications for combat athletes who signed on for MMA careers, only to find the spotlight fading.
This shift dovetails with the promotion’s relocation of headquarters from Singapore to the Cayman Islands and a strategic decision to run most events out of Lumpinee Boxing Stadium in Bangkok—an iconic Muay Thai venue, but a far cry from the MMA arenas where fans expect cage wars.
ONE CEO Chatri Sityodtong recently admitted the company has struggled financially for over a decade, and that profitability is still a pipe dream. When money’s tight, priorities shift—and athlete management often becomes collateral damage.
- Focus moved to kickboxing/Muay Thai event production.
- MMA fighters are sidelined or asked to shift disciplines.
- Reduced MMA event frequency impacts fight opportunities.
- Financial instability breeds broken promises on fighter pay and contract terms.
This constellation casts a long shadow on athlete welfare. Fighters counting on ONE Championship for career development find themselves benched or pushed into sports they didn’t train for originally. It’s as if ONE is tossing fighters to the curb to chase a safer shore—one less bruising but infinitely less lucrative and career-building for MMA athletes.
| ONE Championship Shift | Consequences for Fighters |
|---|---|
| Headquarters moved to Cayman Islands | Less MMA-centric location, logistical hurdles |
| Events concentrated in Lumpinee Boxing Stadium | Muay Thai/kickboxing focus, marginalizes MMA |
| Financial struggles revealed | Delayed or missing fighter payments, contract rigidity |
| MMA events reduced annually | Fewer fight slots; athletes lose career momentum |
Fighters stuck in this system aren’t just losing fights—they’re losing prime years of their careers. Think of it like training for a marathon and suddenly being told to take pole vaulting lessons. It’s awkward, unplanned, and career-wrecking. And for those fighters who try to speak up or escape the quagmire? Well, the legal battles and blacklisting rumors are enough to make any athlete think twice. For more on the darker side of fight promotions, it’s worth digging into stories of fighters competing without pay, spotlighting the thin veneer between opportunity and exploitation.
Fighter solidarity and competition: Stories from Reinier de Ridder and Marcus ‘Buchecha’ Almeida
What happens when a fighter not only survives but thrives after bumping heads with a tumultuous promotion? You get Reinier de Ridder and Marcus “Buchecha” Almeida—two former ONE teammates who now share the “been there, done that” look in UFC’s bright lights.
Buchecha, a jiu-jitsu titan who joined the UFC after years stuck in ONE’s maze, praises De Ridder as an inspiration. Their bond isn’t just about friendship—it’s a badge of honor in the MMA world, forged through frustration, resilience, and the dogged pursuit of career freedom.
- Shared struggles under ONE’s restrictive contracts
- Mutual support through career transitions
- Symbolic representation for trapped athletes in Asia
- Highlighting cracks in athlete welfare within big promotions
De Ridder’s blunt assessment of ONE isn’t just sour grapes. It’s a clarion call that the fight world needs to sit up and really rethink athlete management. When a top-tier talent goes public with accusations of career ruin, the entire mixed martial arts community should take notice and start asking the hard questions. How can combat sports promotions balance business interests without sacrificing fighter welfare? How many careers have been quietly throttled? And what role can managers, commissions, and fans play to ensure fighters aren’t just pawns?
| Fighter | ONE Tenure | UFC Debut | Current Status | Notable Career Highlights |
|---|---|---|---|---|
| Reinier de Ridder | 2019 – 2023 | Nov 2024 | UFC contender, 3-0 | Two-division ONE champ, UFC upset vs Bo Nickal |
