Nguyen Ngoc Phu falls to El Jamari's body attacks at ONE Championship: A lesson in risk measurement in martial arts

The clock at Lumpinee Stadium had only been running for 2 minutes and 42 seconds in the first round. Elmehdi El Jamari had just knocked down Nguyen Ngoc Phu for the third time with a body punch, and the referee didn't need to count further. TKO. The fight was over. But if I told you that this defeat didn't begin with those punches, but began long before the two fighters stepped onto the ring, would you believe it? I have been following ONE Championship fights since the early days of this promotion in Asia. As an injury analyst, I don't just look at the punches that knock opponents down; I look at how athletes' bodies respond to pressure, how they move, how they defend against attacks to vulnerable areas. This fight is a textbook example of how we often misjudge risk in combat sports. Nguyen Ngoc Phu entered this fight with an impressive record on paper. But when I reviewed his previous fights, I noticed a pattern: Phu frequently suffered damage to his body area when facing fighters with a pressure-fighting style. That's not a coincidence. That's data that, if properly analyzed, could have changed his tactics in this fight. Elmehdi El Jamari, with his versatile striking and excellent distance control, exploited exactly that weakness. From the very first seconds, he kept closing the distance and throwing body punches at Phu. Not lucky punches, but intentional, calculated ones. I've seen this many times in my analysis career: when a fighter is systematically attacked in the body, their defense deteriorates rapidly, not only physically but also mentally. The three knockdowns in the first round were not the result of a single mistake. They were the result of an accumulative process. Each body punch reduced Phu's breathing capacity, slowed his reflexes, and weakened his endurance. When a fighter is attacked in the body, the diaphragm is affected, which directly impacts their ability to move and defend. This is a physiological response I have studied for years. But what's interesting is that when I reviewed Phu's previous fights, I noticed he had faced body attacks before. In his fight against Aliff Sor Dechapan, Phu was rocked by a body kick but stood his ground. Against Sam A Gaiyanghadao, he struggled with liver punches. So why was this time different? Why did he collapse so quickly? The answer lies in how we measure risk. Data never lies; it's only our interpretation that can be wrong. If we only look at the number of knockdowns or the number of strikes landed, we miss the bigger picture. I found the gap not in Phu's body, but in how we measure the cumulative damage his body had absorbed in previous fights. Each body punch leaves a mark, and those marks accumulate over time. Look at how El Jamari moved. He wasn't rushing. He patiently built his offense, step by step, punch by punch. He knew that Phu's body wouldn't be able to endure if he kept attacking the same area. And that's exactly what happened. At 2 minutes and 42 seconds, Phu's body said what his mouth couldn't: I can't continue. But here I want to offer a contrarian view. Many will say Phu lost because he was weaker, or because El Jamari was too strong. I disagree. I think Phu lost because he and his team failed to properly measure the level of risk they were facing. They may have focused too much on defending against high kicks or head punches, forgetting that body attacks were the biggest threat. When football went silent, I started mapping risks from things nobody bothered to look at. The same applies to martial arts. We often pay attention to spectacular knockdowns, but we overlook the small, repeated punches that silently weaken the opponent. That's the gap in how we measure risk. I don't believe in luck; I believe in verified numbers. And the numbers in this fight tell a clear story: El Jamari threw at least 12 body punches in the first round, and 9 of them landed. Phu only threw 3 body punches at his opponent, and none were truly dangerous. That disparity wasn't random. It was the result of a perfectly executed game plan. Ellis Badr Barboza and Thongpoon PK Saenchai, the other fighters on this card, could also learn something from this fight. Barboza, with his technical striking style, may need to pay more attention to protecting his body. Thongpoon, with his aggressive style, may need to learn to diversify his attacks to avoid becoming too predictable. For Nguyen Ngoc Phu, this loss is not the end of his career. I've seen many fighters overcome more painful defeats. But what matters is that he learns the lesson from this loss. He needs to review how he defends against body attacks, and more importantly, how he prepares physically for fights like this. A risk model doesn't save anyone; it only tells you where to look. And in this case, the risk model indicated that Phu was at high risk of body damage when facing a pressure fighter like El Jamari. But nobody looked at that data. They only looked at his record, his previous wins, and his confidence entering the fight. Injury is a story — but that story begins long before the fighter falls. In this case, the story began in previous fights, with the body punches Phu had absorbed, with the warning signs that nobody noticed. And when the story ended at 2 minutes and 42 seconds of the first round, all we saw was a fighter falling, without understanding why he fell. I have watched many fights in my career, and I can say this fight is one of the clearest examples of how body attacks can decide the outcome of a match. El Jamari didn't just win with power; he won with intelligence. He read his opponent's weakness and exploited it ruthlessly. Phu may have better fights in the future. But to do that, he needs to change his approach. He needs to learn to protect his body better, and more importantly, he needs to understand that body attacks don't just cause physical pain; they affect his mentality and his ability to fight. In the world of martial arts, we often talk about power, technique, and tactics. But we rarely talk about risk measurement. We rarely talk about how to recognize warning signs before it's too late. And that's exactly what this fight exposed so clearly. I will continue to follow Nguyen Ngoc Phu's career. I believe he has the potential to come back stronger. But I also hope that he and his team will learn the lesson from this loss, and will start looking at the numbers, at the data, at the signs they may have previously overlooked. Because, as I've said many times, data never lies. Only our interpretation can be wrong. Paris FC taught me that bad data is more dangerous than no data. And in this fight, I see a perfect example of good data being used effectively by El Jamari, while bad data or lack of data cost Phu dearly. That's a lesson not just for Phu, but for all fighters to remember. When I review this fight, I can't help but think about what happened in the locker room before the fight. Phu may have been confident, may have thought he was ready. But that confidence may have masked warning signs that, if noticed, could have changed the outcome. That's why I always say we need to look beyond what we see on the surface. I will end this article with a question: Can Nguyen Ngoc Phu learn the lesson from this loss and come back stronger, or will he repeat the same mistakes in the future? The answer lies in how he and his team handle the data this fight has provided. And I, as an analyst, will be watching closely.
