Jiri Prochazka has commented on his knockout loss to Carlos Ulberg, rejecting the notion that he showed mercy to his injured opponent. Prochazka explained that he lost concentration and relaxed, seeing Ulberg as an easy target and recklessly pursuing a finish, for which he paid the price. He referenced his favorite book, Miyamoto Musashi's "The Book of Five Rings," which emphasizes that a warrior should focus only on victory, not the strength of strikes. Prochazka acknowledged the fight could have been conducted more intelligently but attributed the loss to low fight IQ rather than compassion. He has apologized to fans for his performance and vowed to return stronger, while also mentioning he will soon witness "the miracle of life," suggesting a personal life event.
Jiri Prochazka has opened up about his knockout defeat to Carlos Ulberg, offering a candid self-assessment that dismisses any suggestion he went easy on his opponent during the fight.
The Czech standout, ranked second in the light heavyweight division at 33 years old, carries a professional record of 32-6-1 and is one of the most aggressive finishers in the 205-pound weight class. Fighting out of Jetsaam Gym Brno, Prochazka stands six-foot-three with an 80-inch reach and averages 5.69 significant strikes per minute at 55 percent accuracy — numbers that reflect his relentless attacking style.
Prochazka was direct in his explanation of what went wrong. He said he lost concentration after seeing Ulberg as a vulnerable target, relaxed prematurely, and chased a reckless finish as a result. He drew on Miyamoto Musashi's "The Book of Five Rings" to frame the lesson, noting the text's teaching that a warrior must remain fixed on victory rather than the force of individual strikes. He attributed the performance to poor fight IQ rather than any act of mercy, and apologized to fans for falling short of his own standards.
Ulberg, the New Zealand fighter known as "Black Jag," is ranked third in the same division at 35 years old with a record of 15-1-0. Fighting out of City Kickboxing, the six-foot-four knockout artist actually leads Prochazka in significant strikes per minute at 6.54, also at 55 percent accuracy, and the win moves him further into title contention.
Why it matters
- Prochazka's loss drops him to second in the rankings while Ulberg consolidates third, tightening the logjam below the light heavyweight title
- A self-diagnosed lapse in focus from a former champion raises questions about where Prochazka fits in the division's near-term future
- Prochazka also referenced an imminent personal life event, describing it as witnessing "the miracle of life," which may influence his timeline for returning to competition
