Alberto “El Indio” Blas has never lost a bare knuckle fight. Not once. Across two promotions, multiple weight classes, and nine professional contests, the Cuban-born Miami fighter has stopped every opponent he has faced. He left the Bare Knuckle Fighting Championship (BKFC) as its undefeated Bantamweight champion and moved to BKB Bare Knuckle Boxing where he became the inaugural Super Featherweight champion. In 2026, he was inducted into the Bare Knuckle Boxing Hall of Fame. At 31 years old, his story is still being written.
Early Life and Path to Bare Knuckle Boxing
Alberto Blas was born in Matanzas, Cuba, one of the country’s most culturally rich provinces located on the north coast of the island. He began training in combat sports at four years old, a starting point that reflects the seriousness with which Cuban athletes approach their craft from childhood. Cuba has produced some of boxing’s greatest champions across the generations, and that tradition shaped Blas’s early development as a fighter.
His family history influenced his nickname. “El Indio” is not just a ring name. It represents a connection to his roots and a legacy he carries into every fight. He has spoken publicly about fighting for his family and for the memory of where he comes from as much as for himself.
Blas relocated to Miami, Florida, where he built his professional career from the ground up within South Florida’s tight-knit combat sports community. The Cuban diaspora in Miami gave him a base of support and a community that understood what he was building. He trained under the guidance of Manny del Rio, Eduardo Concepcion, Vil Vergara, and Eric Castaño, assembling a coaching team that has developed him across multiple dimensions of bare knuckle competition.
His decision to compete exclusively in bare knuckle boxing, rather than gloved boxing or MMA, reflects a deliberate career choice. He has never competed in a gloved professional contest. Everything he has built, every title, every win, every reputation point, has come without gloves.
What Is BKFC and Why It Matters
The Bare Knuckle Fighting Championship (BKFC) is the world’s largest and most established bare knuckle combat sports organisation. Founded in 2018 by David Feldman, BKFC introduced the sport to a global audience through a standardised format that includes a smaller square ring called the Squared Circle, no wraps on the hands, and rounds that reward aggression and punch output.
BKFC differs from traditional boxing and MMA in ways that go beyond the absence of gloves. Without the padding that gloves provide, the risk of cuts increases significantly, and the premium on accurate, hard punches rather than volume at range changes how fighters approach both offense and defence. Fighters who succeed in BKFC tend to combine durability, accuracy, and the willingness to engage at close range where bare knuckle damage accumulates fastest.
Alberto Blas is also associated with BKB Bare Knuckle Boxing, a separate organisation based in Miami that operates across the United States and the United Kingdom. Both organisations compete in the same combat sports space and have produced their own champions. Blas has held titles in both, making him one of the rare fighters to achieve championship status across two different bare knuckle promotions. The crossover between bare knuckle boxing and MMA continues to grow, with several former UFC fighters making the transition to gloveless competition in recent years, a trend explored in our UFC vs Boxing breakdown.
Alberto Blas BKFC Record
Alberto Blas joined the Bare Knuckle Fighting Championship and built a 6-0 record before departing the organisation as the reigning Bantamweight champion. His BKFC record includes six wins, all by knockout or TKO, with the majority of finishes coming inside the first round.
His BKFC tenure established the template that has defined his entire career. He entered fights as a physical aggressor who used his southpaw stance to create angular problems for opponents, landed clean shots with consistent power, and closed fights quickly once the advantage was established. He did not give opponents the opportunity to recover or rebuild their game once he found his range.
The highlight of his BKFC run was winning and then defending the Bantamweight title. His most notable BKFC performance came at BKFC 66, where he defended his Bantamweight title against the previously unbeaten Ryan Reber 6-0-0 at Seminole Hard Rock Hotel and Casino in Hollywood, Florida. The fight was sold out. Reber entered as the number two contender in the division and an undefeated prospect. Blas dropped him twice and finished the fight in just 56 seconds of the first round, extending his record to 6-0 with six consecutive first-round stoppages.
After the fight, Blas addressed the bantamweight division directly. He called out every fighter at 135 pounds who was willing to face him and asked who was next. The answer from the division was silence. No credible challenger stepped forward, and Blas eventually made the decision to leave BKFC voluntarily while still champion, taking his undefeated record into BKB Bare Knuckle Boxing where a new challenge and a new division awaited.
| Stat | BKFC Record |
| Wins | 6 |
| Losses | 0 |
| KO/TKO Wins | 6 |
| First Round Finishes | 6 |
| Title Fights | 1 (won, defended once) |
| Departed | As reigning Bantamweight Champion |
BKB Bare Knuckle Boxing Career
After leaving BKFC as champion, Blas signed with BKB Bare Knuckle Boxing and moved down in weight to the Super Featherweight division at 130 pounds. The transition represented a new challenge, a new promotion with its own roster, its own format, and its own champions waiting to be tested.
His BKB debut came in August 2025 and produced another first-round stoppage. The result confirmed that his BKFC performances were not a product of weaker opposition. He was doing the same damage at a new weight class against fighters who had never seen him before.
His biggest BKB moment came at BKB 50 on January 31, 2026, at the James L. Knight Center in Miami, the promotion’s 50th event and a milestone card that carried significant commercial weight. Blas was booked to fight Brandon Birr for the inaugural BKB Super Featherweight Championship, but Birr withdrew through injury. Harold McQueen stepped in as the replacement. The fight was the deepest challenge Blas had faced to that point. McQueen pushed the pace in the early rounds and showed enough pressure to keep the fight competitive longer than any of Blas’s previous opponents. Blas eventually found his opening and stopped McQueen at 2:20 of the third round, becoming the inaugural BKB Super Featherweight champion. It was the first time in his professional bare knuckle career that a fight had reached the third round.
The third-round finish produced a more complete picture of Blas as a fighter. He could manage adversity. He could work through a difficult patch. He was not simply a first-round finisher whose game fell apart when opponents survived early pressure. He was a championship-level competitor who could adapt.
His most recent performance came at BKB 58 on August 29, 2026, at the James L. Knight Center in Miami. The original Birr matchup was rescheduled from BKB 50, and this time Birr arrived as the number one contender and former BKB Featherweight champion. The rematch that BKB fans had been waiting for finally delivered. Blas stopped Birr with a clean punch at 1:57 of the first round, extending his overall bare knuckle record to 9-0 with nine knockouts and moving to 3-0 in BKB with the Super Featherweight title retained.

Fighting Style and Strengths
Alberto Blas fights from a southpaw stance at 5’8″ with a reach of 70 inches. His approach to bare knuckle combat is built on three pillars explosive entry, angular positioning, and clean power on the finish.
The southpaw stance creates natural alignment problems for orthodox fighters in bare knuckle competition. His left straight lands at angles that right-handed fighters are not naturally positioned to defend, and his right hook over the top becomes a setup shot that orthodox opponents struggle to read when it is mixed with lead hand jabs and body shots.
His explosiveness has been one of the most commented-on aspects of his career by training partners and coaches. He attacks in short, sharp bursts rather than with sustained volume, preserving energy while generating enough impact in each sequence to create lasting damage on opponents who do not cover correctly. In bare knuckle fighting, where cuts and swelling accumulate faster than in gloved competition, a few clean shots in the right location can close an eye or open a cut that changes the course of a fight permanently.
His body attack is another underrated dimension of his game. In fights where opponents have attempted to survive by lowering their chin and tightening their guard, Blas has shifted to body work that breaks posture and creates the opening he needs for the finishing shot to the head. The McQueen fight demonstrated this adaptability most clearly.
His defensive game relies on movement and range management rather than passive blocking. He tends not to stand in the pocket and absorb punishment. He creates angles, resets his position, and attacks from ranges and directions that opponents have not established their defences for.
Hall of Fame Induction and Legacy
In 2026, Alberto Blas was inducted into the Bare Knuckle Boxing Hall of Fame. The induction recognised his combined achievements across two promotions, his undefeated record, and his role in raising the profile of bare knuckle competition as a legitimate global combat sport.
Blas spoke about the induction with characteristic directness. He said it meant everything to him that his name would stay in the sport permanently. He said future young fighters and young people in the sport would see his name in the Hall of Fame and that fulfilling that goal was one of the most meaningful moments of his career.
The induction also reflects where bare knuckle boxing sits as a sport in 2026. A Hall of Fame that carries genuine meaning represents institutional maturity. The sport that BKFC and BKB have built across the past eight years has produced enough history, enough champions, and enough memorable performances to justify preserving those records permanently. Blas stands near the top of that list as one of the most accomplished active competitors in the sport’s history. For comparison, the standard of perfection in combat sports is best illustrated by fighters like Khabib Nurmagomedov, whose undefeated legacy across MMA is covered in our Top 5 Undefeated UFC Fighters of All Time article.
His stated goal is to become a champion across three different weight classes. He holds titles at Bantamweight and Super Featherweight. A move to Featherweight would complete the ambition he has spoken about publicly. Based on the trajectory of his career and the quality of his performances, there is no reason to believe that goal is beyond his reach.
What Drives Alberto Blas
The personal story behind Blas’s career is as compelling as the record itself. He is a dedicated husband and father whose family provides the motivation that gets him out of bed and into the gym on days when the training is difficult and the comfort of staying home would be easier.
He has spoken about the sacrifices the sport demands. In the build-up to BKB 58, he revealed that he had not seen his children for approximately two months while preparing for the Brandon Birr rematch. The separation was not easy. He framed it as the price of building the life he wants for them. His children, he said, give him the strength and the mindset to keep pushing when nothing else would.
That family-first motivation has been a consistent thread through every interview he has given. The fights are not just about records, titles, or rankings. They are about providing for a family and building a legacy his children can point to with pride. The Hall of Fame induction takes on additional meaning in that context. His name in the record books is something he will leave behind for them. The same fighting spirit that drives Cuban-born champions in combat sports is reflected across the broader MMA world, including in our coverage of the Best MMA Fighters From Pakistan — fighters who share that same family-driven motivation to succeed on the global stage.
