Carlos Ulberg reveals injury nearly forced corner stoppage before first-round finish

Carlos Ulberg has revealed he was carrying an injury at UFC 327 that had his corner on the verge of stopping his fight between rounds, forcing him to pursue a finish inside the opening minute of the first frame.

The New Zealand light heavyweight, who competes out of City Kickboxing, disclosed after the April 11 event that he was fully aware his team would intervene if the bout extended beyond round one. Rather than let that happen, Ulberg made a deliberate decision to turn up the aggression and power early, targeting a knockout before his corner could pull him out. He succeeded, adding another first-round finish to his résumé despite the undisclosed injury limiting his capacity to continue. The specific nature of the injury has not been revealed.

Ulberg, nicknamed Black Jag, enters the post-fight period at 15-1-0 and ranked third in the light heavyweight division. The 35-year-old stands six-foot-four with a 77-inch reach, and his offensive output makes him one of the more dangerous strikers in the weight class. He lands 6.54 significant strikes per minute at a 55 percent accuracy rate, numbers that reflect both his volume and efficiency on the feet.

Why it matters

• Ulberg's win came under significant physical duress, raising questions about the full extent of the injury and his timeline for a return.
• Sitting at number three in the light heavyweight rankings, a title shot or a bout with a top-two contender remains a realistic next step.
• The revelation underscores how his elite finishing instincts allowed him to override a potentially fight-ending situation and deliver a clean result regardless.
