Chimaev's loss removes him from undefeated fighters list

Khamzat Chimaev's name has been removed from the list of active undefeated fighters with more than ten wins in major promotions after he suffered a split decision loss to Sean Strickland at UFC 328 on May 9, 2026. The defeat leaves Chimaev with a professional record of 15-1.

Chimaev, 32, represents the United Arab Emirates and trains out of Allstars Training Center. Ranked first in the middleweight division and tenth in the pound-for-pound standings, he had built one of the most feared records in the sport. His grappling output remains exceptional, with 5.29 takedowns per fifteen minutes, and he connects on 60 percent of his significant strikes — the highest accuracy figure among the fighters mentioned in this story.

Strickland, the reigning middleweight champion, improves to 31-7 with the victory. The 35-year-old American, who trains at Xtreme Couture and stands six-foot-one with a 76-inch reach, is one of the most active strikers in the division at 6.04 significant strikes landed per minute.

Why it matters

• Chimaev's removal ends one of the highest-profile undefeated runs in the 185-pound division
• The updated list, compiled from Tapology and Sherdog records, still features several elite unbeatens including Movlid Khaybulaev (24-0-1-1NC), Usman Nurmagomedov (21-0-1NC), and Movsar Evloev (20-0)
• Ilia Topuria, ranked second at lightweight and first in the pound-for-pound rankings, remains on the list — though the verified data now reflects his record at 17-1, suggesting his status may also require a separate update
• The list excludes retired fighters and those inactive for more than two years, keeping the rankings a reflection of current competitive activity
