Argentina’s formidable UFC welterweight Santiago Ponzinibio claimed an impressive seven-fight winning streak in 2018. His knockout victory over Neil Magny established him as a rising star with championship aspirations but a string of health issues so soon launched his career and staked his future squarely in the Octagon.
The Injury that Started it All
The trouble started in 2018 when Ponzinibbio suffered a serious hand injury. He underwent surgery to repair the damage, but what seemed to be his routine turned into a serious health problem. Shortly after the surgery, Ponzinibbio encountered an unexpectedly serious complication: an infection that would take years to resolve.
A Terrible Double Infection
Ponzinibbio’s surgical recovery was marred by severe complications. He was diagnosed with plague and pseudomonas, two dangerous bacteria. Pseudomonas is a particularly insidious pathogen found in soil and water, and is known to cause serious infections, especially in compromised immune systems.

The infection led to a prolonged hospital stay. Ponzinibbio initially spent a week in the hospital receiving treatment. However, the illness persisted and she developed a fever of 300 degrees Fahrenheit [103°C]. This forced her to be hospitalized for ten days, during which time she received intensive care and medication for a month one of the.
Limitations and Impact
Despite aggressive treatment, Ponzinibbio struggled to recover. When doctors diagnosed a bone tumor through an MRI scan, she faced new challenges. The discovery was cruel: the infection severely threatened his career. Ponzinibbio was told he would never fight again, a devastating blow to the Argentine fighter who had worked so hard to reach the top of the UFC.
Back to the Octagon
Ponzinibbio was widely expected to return to the UFC in 2021. His comeback fight was against Jingliang Li at UFC on ABC 1, where he faced a tough reality test in his first knockout defeat. This setback was disappointing, but Ponzinibbio’s resilience shone through as he bounced back with a unanimous decision victory over Miguel Baeza.
But the road to redemption was fraught with challenges. Ponzinibbio lost twice more in close contests against Geoff Neal and Michelle Pereira. These setbacks did not dampen his spirit and he was determined to prove himself. His fight against Alex Moreno at UFC 282 was a huge success, Ponzinibbio earned a TKO victory that showcased his fighting spirit.
But his last fight against Kevin Holland at UFC 287 ended in another defeat, the seventh of his career. Despite the setbacks, Ponzinibbio’s determination to win is unwavering.
Looking Ahead: Ponzinibbio and Salikov
In preparation for his main event matchup with Muslim Salikhov at UFC Denver, Santiago Ponzinibbio is currently training. Salikhov is a gifted fighter who has a 19–5 record and is coming off a two-fight losing run. Although this encounter presents a significant obstacle for Ponzinibbio, it also offers a chance to alter his welcome and revitalize his career.
During his path through struggle, Ponzinibbio experienced both excruciating lows and amazing highs. Fighters are excited to see if he can bounce back from his recent losses and win back the title of welterweight champion as he gets ready to return to the Octagon.
