Last week, Bare Knuckle Boxing (BKB) announced the signing of former interim champion and fan-favorite warrior Alfredo “El Perro” Angulo (26-8, 21 KOs in traditional boxing) to a multi-fight deal, adding another proven striker to its rapidly growing roster. Angulo is expected to make his BKB debut July 18 at BKB 56 in Los Angeles. A relentless pressure fighter known for his toughness and all-action style, Angulo brings decades of high-level experience to BKB. The Mexicali native built a decorated professional boxing career that included capturing the WBO interim light middleweight title from 2009 to 2010.

 

Before turning pro in 2005, Angulo compiled nearly 100 amateur bouts, highlighted by a victory over future world champion Tim Bradley. He also represented Mexico on the international stage, earning medals at the 2002 Central American and Caribbean Games and the 2003 Pan American Games, before competing in the 2004 Olympic Games.

 

Throughout his career, Angulo faced a who’s-who of elite competition, including Canelo Alvarez, Erislandy Lara, Kermit Cintron and Sergio Mora, earning a reputation as one of boxing’s most fearless and entertaining fighters. His aggressive style and durability have already proven to be a natural fit for bare knuckle.

 

“This is a huge signing for BKB,” said BKB CEO David Tetreault. “Alfredo Angulo is the definition of a warrior. Fans know exactly what they’re going to get every time he steps into the ring—heart, pressure, and nonstop action. He’s built for bare knuckle, and we’re excited to showcase him on the BKB stage.”

 

Angulo’s journey has been marked by resilience as much as success. A highly publicized visa dispute in 2012 saw him detained for eight months, a challenge he overcame with perspective and gratitude—famously donating his hair to Locks of Love during that time to support children battling cancer.

 

“I’ve fought the best in the world, and I’m still hungry,” said Angulo. “Bare knuckle brings out a different kind of fighter, and that’s who I am. I’m ready to give the fans exciting fights and show them that ‘El Perro’ still has a lot left.”

 

From its origins in 2015 as BYB Extreme Fighting Series, founded by MMA pioneer Dhafir "Dada 5000" Harris and Mike Vazquez, BKB has transformed bare knuckle boxing into a regulated, globally broadcast promoter through strategic acquisitions, including the original UK-based BKB in 2024 and Bad To The Bone in 2025, and a fighter-first philosophy that emphasizes athlete welfare and opportunity.
