Azamat Murzakanov suffered his first career defeat, getting knocked out by Paulo Costa at UFC 327, ending his 16-0 record. The updated rankings of undefeated fighters active in major promotions with over 10 wins show several changes. Radjabali Shaidullaev improved to 18-0 with a TKO victory over Yuta Kubo at RIZIN LANDMARK 13. Renat Khavalev reached 12-0 by defeating Raufeon Stots by decision at PFL Chicago. Mitchell McKee joined the list at 11-0 after beating Sergio Pettis by decision at PFL Chicago. The list is maintained using records from Tapology and Sherdog, tracking fighters who have been active within the past two years and have not retired.
Azamat Murzakanov's perfect professional record came to an end at UFC 327 on April 11, when Paulo Costa stopped him by knockout, handing the Russian light heavyweight his first career loss.
Murzakanov, 37, had entered the bout at 16-0 and ranked 12th in the UFC light heavyweight division. Fighting out of K Dojo Warrior Tribe and known as "The Professional," the southpaw had built his reputation on clean, accurate striking, landing 4.7 significant strikes per minute at a 57 percent accuracy rate across his career. That unblemished record is now gone, his ledger moving to 16-1.
Costa, known as "The Eraser," delivered the finish for the 35-year-old Brazilian, who now stands at 16-4 and holds the 13th ranking in the middleweight division. Fighting out of Team Borracha, Costa is one of the more prolific strikers in the sport, averaging 6.26 significant strikes per minute at a remarkable 58 percent accuracy rate. The knockout adds to a highlight reel that has long made him one of the most dangerous finishers in the 185-pound class, though here he competed against a light heavyweight.
Why it matters
- Murzakanov's perfect record was one of the more notable undefeated streaks among fighters active in major promotions, and its end reshapes the landscape of that group.
- Costa's performance at light heavyweight raises questions about his long-term divisional home and his standing in the middleweight rankings at 13th.
- Murzakanov remains inside the top 15 at light heavyweight despite the loss, keeping him relevant in a competitive division.
Elsewhere on the night of undefeated records, Radjabali Shaidullaev improved to 18-0 with a TKO win over Yuta Kubo at RIZIN LANDMARK 13, while Renat Khavalev reached 12-0 and Mitchell McKee 11-0 following decision victories at PFL Chicago, the latter two results adjusting the broader picture of active unbeaten fighters with more than ten professional wins.
