The Bloody Comeback: How Bare-Knuckle Boxing is Fighting for Legitimacy
One punch could change your life. That's the reality for bare-knuckle boxer Liam Rees, a Welsh carpenter who stepped into the ring and lost his light-middleweight world title, then slumped in a chair with his wife Emma whispering, "No more now babe." But Rees isn't quitting. He's part of a strange, bloody renaissance: bare-knuckle boxing, the oldest form of the sport, is clawing its way back into the mainstream after more than a century in the shadows.
In 2015, there were just 21 licensed bare-knuckle bouts worldwide. Last year, that figure exploded to more than 1,000 across 21 countries. The United States alone hosted at least 65 events in 2025; the United Kingdom was second with 31. And the audience is skewing young. Half of the social media followers for Bare Knuckle Boxing (BKB) promotions fall into the Gen Z and millennial demographics. This isn't a fringe spectacle anymore. It's a serious business, with broadcast deals, celebrity crossovers, and a growing army of fighters willing to bleed for a cheque that rarely covers the bills.
But the rise comes with a price. Brain injury charity Headway has called the trend "hugely concerning." Boxing promoter Eddie Hearn says it's "a little bit barbaric." And yet, fighters like Rees keep coming back for the adrenaline. "Some people think I'm crazy," he admits. So what's really going on in the world of bare-knuckle boxing? Let's step inside.
Inside the Ring: A Fighter's Perspective on Bare-Knuckle Boxing
Liam Rees is 31, a two-time light-middleweight world champion in BKB, and he still works as a carpenter to make ends meet. His camp routine is punishing: three training sessions a day, five days a week, which means he rarely sees his two children on weeknights. "I want to leave a legacy, just to prove to the city I've done something for them," he told BBC Sport. That city is Swansea, and his journey into bare-knuckle boxing began after overcoming substance-abuse issues, when a trainer in his boxing gym introduced him to the emerging combat sport.
Fighting bare-knuckle is different. The ring is half the size of a professional gloved boxing ring, so there's nowhere to hide. "You've got so much adrenaline pumping through your body," Rees says. The result: more cuts, more bruises, more knockouts. BKB president David Tetreault claims that 90% of bouts end in knockout or technical knockout. That's exactly the appeal for some fans. It's raw, it's fast, and it doesn't drag on for twelve rounds of hugging.
The Welshman made his bare-knuckle debut in 2023. He knows the dangers. "One punch could change your life. But I love the sport," he says. That love is real, but it's also a kind of desperation. Bare-knuckle boxing doesn't pay enough to be a full-time career for most fighters. Rees juggles his carpentry business with the demands of a sport that leaves him bloodied and bruised. His wife wants him to stop. For now, he isn't listening.
From Outlaw to Mainstream: The Numbers Behind Bare-Knuckle Boxing's Growth
Bare-knuckle boxing was the original form of boxing, practised for centuries before the Marquess of Queensberry rules introduced gloves in 1867. After that, bare-knuckle fighting became associated with unlicensed brawls on wastelands, a criminal fringe activity. It stayed that way for more than 130 years until the first sanctioned bout in the US state of Wyoming in 2018. That event cracked the door open, and the sport has been kicking it down ever since.
According to data from BoxRec, the number of licensed bare-knuckle bouts grew from 21 in 2015 to over 1,000 in 2025. That's a compound annual growth rate that would make any tech startup jealous. The UK is now a key battleground, hosting 31 events in 2025. BKB promotions, one of two major international promoters (alongside US-based BKFC), caps attendance at 2,000 per event and says they generally sell out. The fights are broadcast in more than 60 countries, with partnerships including VICE TV and TalkSport.
Audience data is telling. Tetreault claims that 50% of BKB's social media audience is Gen Z or millennial. These are viewers who grew up on UFC, on violent video games, on content that is immediate and visceral. Bare-knuckle boxing, with its shorter bouts (maximum six three-minute rounds in BKB, two-minute rounds in BKFC), fits perfectly into a world of short attention spans and bloodlust. The sport isn't just growing. It's resonating with the next generation of fight fans.
Is It Safer Than Gloved Boxing? The Medical Debate
It seems counterintuitive to argue that hitting someone with your bare fists is safer than wearing gloves, but that's exactly what BKB president David Tetreault claims. "The fighters have to be taking care of their hands. They can't hit as hard," he told BBC Sport. Gloves, he argues, allow boxers to punch the skull with greater force because the padding protects the hand. Without that padding, fighters are more cautious about how and where they strike, because breaking a hand is a real risk.
Then there's the duration. Gloved professional boxing matches can go twelve rounds of three minutes each. Bare-knuckle bouts are capped at six rounds (BKB) or two-minute rounds (BKFC). "The difference is it's not the continual punching," Tetreault says. Shorter fights mean fewer cumulative blows to the head, potentially reducing the risk of chronic traumatic encephalopathy (CTE) and other brain injuries. It's a plausible argument, though one that lacks long-term data.
Brain injury charity Headway isn't buying it. Chief executive Luke Griggs said he is "hugely concerned" about the sport's rise and the "glamourisation of a sport that's going to be taken out into the streets." He worries that the bloody spectacle normalises violence, especially among impressionable young viewers. Dr. Louis Durkin, president of the Association of Ringside Physicians, has also expressed caution, though the source material cuts off before his full comments. The reality is that both gloved and bare-knuckle boxing carry serious risks. The question is which one does a better job of managing them. For now, the evidence is too thin to call it one way or the other.
Celebrity Crossovers and the Battle for Young Audiences
When Paulie Malignaggi defeated Tyler Goodjohn by split decision in Leeds last October, the crowd wasn't short of star power. Former multiple super-middleweight world champion Carl Froch was there. Two-time featherweight champion Josh Warrington. Two-weight world champion Natasha Jonas. These are names that fill arenas in gloved boxing, and they came to watch bare-knuckle. Malignaggi, a former world champion himself, is one of several retired boxers to cross over, alongside Lee Selby and James DeGale. Their participation lends credibility and draws curious fans.
"It's a blood sport, people do have a blood thirst to watch this sport," Malignaggi told BBC Sport. "It's more action packed and I think the misconceptions are going to slowly go away once people watch it more and more." He sees bare-knuckle boxing as the natural evolution of combat sports for a generation that finds standard boxing too slow and technical. Natasha Jonas was "impressed by the set-up" but doubts she'll ever compete. Eddie Hearn, the UK's most prominent boxing promoter, is more blunt: "It's a little bit barbaric for me, I am a boxing purist."
The tension between purity and spectacle is the heart of bare-knuckle boxing's identity crisis. It wants to be taken seriously as a sport, not a freak show. But the very things that attract young audiences (the blood, the knockouts, the brutal immediacy) are exactly what alarm medical experts and traditional boxing insiders. BKB's social media strategy leans hard on those gory highlights, and it's working. Fifty percent of their followers are under 35. That's a number the established boxing establishment can only dream of.
What the Future Holds for Bare-Knuckle Boxing
Bare-knuckle boxing is at a crossroads. It has momentum, money, and a hungry audience. But it still operates in a regulatory grey area in many jurisdictions. The UK and US have licensed events, but the sport is banned or unregulated elsewhere. The absence of a unified global body means rules vary wildly, and fighter safety standards are inconsistent. For the sport to achieve true legitimacy, it will need consistent regulation, proper medical oversight, and a willingness to address the risks head on.
Fighters like Liam Rees show the human cost and the human drive. "One punch could change your life," he says. He knows it. He steps in anyway. For every fighter, every promoter, every fan, the question is whether that gamble is worth it. The sport's rising popularity suggests many are betting yes. But as Headway's Griggs warns, the glamourisation of violence has broader social consequences. Bare-knuckle boxing may be a thrilling spectacle, but it's also a mirror reflecting our own appetite for risk and reward.
The numbers suggest this trend isn't slowing down. More countries are hosting events, more broadcasters are signing deals, more retired champions are lacing up. Whether it ever matches the mainstream reach of gloved boxing remains to be seen. But one thing is certain: bare-knuckle boxing is no longer a fringe curiosity. It's a serious contender in the combat sports world, and it's not going away quietly.
