2025 has not been kind to boxing fans, especially in these last few months. From the beloved Ricky Hatton (46) to 17-year-old Arturo Gatti Jr., they’ve mourned the loss of one too many lives. Japanese talents Shigetoshi Kotari and Hiromasa Urakawa also tragically lost their lives in August, after sustaining brain injuries on the same card. Now, the boxing world is in mourning again over the tragic death of seventeen-year-old Mexican prospect Kiara Rubalcaba, who passed away after injuries from a sparring session. Kiara Rubalcaba had only begun boxing two months prior. As reported on Instagram by Supreme Boxing from ‘latinboxsports’: “Kiara Rubalcaba, a 17-year-old girl, died after suffering serious injuries during a sparring session at a gym in the Potreros del Oeste neighborhood of Aguascalientes, Mexico. According to initial reports, Kiara had only been training in boxing for two months and was matched with a more experienced opponent. After receiving several blows to the head, she collapsed and was rushed to the hospital, where she died hours later.” ADVERTISEMENT Article continues below this ad Combat sports have long sparked debate over their safety and risks. While the UFC has often been criticized as “human cockfighting,” it is boxing that has historically claimed the most lives. Among its tragic cases, Prichard Colon, once a promising talent, suffered permanent paralysis on his left side after a single misstep by an opponent, leaving him dependent on a computer for communication for the rest of his life. Although details about Kiara’s death remain limited, sparring fatalities are far less common than those in official bouts. Her young age and limited experience have struck a chord with fans and critics alike, reminiscent of Australian boxer Dwight Ritchie, who tragically died under similar circumstances while sparring in 2019. The incident has sparked a mix of grief and outrage among fight fans, with some directing sharp criticism at the coach.
