Khamzat Chimaev's perfect professional record came to an end at UFC 328 on May 9, when Sean Strickland claimed a split decision victory over the previously undefeated contender, handing "Borz" the first loss of his MMA career.
Chimaev, 32, entered the fight ranked first in the middleweight division and tenth pound-for-pound, carrying a 15-0 record that had made him one of the most talked-about unbeaten fighters in the sport. The UAE-based Allstars Training Center product brought elite grappling into the cage, averaging 5.29 takedowns per 15 minutes and a striking accuracy of 60 percent. His record now stands at 15-1.
Strickland, the reigning middleweight champion, improved to 31-7 with the win. The 35-year-old American out of Xtreme Couture has built his title reign on relentless output, landing 6.04 significant strikes per minute with a 76-inch reach that allows him to control range and volume over the course of five rounds.
Elsewhere at UFC 328, Baysangur Susurkaev moved to 12-0 after submitting Jorden Santos, keeping himself firmly in the conversation among the sport's top undefeated prospects. At ACA 203, Alikhan Musaev improved to 11-0 by defeating Furkhat Komilov by decision.
The loss to Chimaev updates the broader picture of long undefeated runs in major global promotions. Movlid Khaybulaev remains among the most remarkable, carrying a 23-0-1 record at age 35 while averaging a staggering 20.89 takedowns per 15 minutes and a striking accuracy of nearly 76 percent. Usman Nurmagomedov's 21-0-1 NC also keeps him near the top of that list.
Why it matters
- Chimaev's first professional defeat reshapes the middleweight title picture, with the division's top-ranked contender now carrying a loss
- Strickland's title defense against a 15-0 opponent further cements his standing as middleweight champion
- Susurkaev's continued unbeaten run at 12-0 strengthens his case as a future contender to watch
- The broader undefeated tracker loses its highest-profile name, leaving Khaybulaev and Nurmagomedov as the headline acts
