Khamzat Chimaev's remarkable unbeaten run came to an end on May 9 at UFC 328, where Sean Strickland earned a split decision victory to hand the middleweight contender the first loss of his professional career.
Chimaev, known as "Borz," entered the fight at 15-0 with one no contest and carried the number-one middleweight ranking and a top-ten pound-for-pound position into the contest. The 32-year-old fighting out of the United Arab Emirates and training at Allstars Training Center had built his reputation on overwhelming opponents through a combination of volume wrestling and precise striking, averaging 5.29 takedowns per 15 minutes and landing 60 percent of his significant strikes. Standing six-foot-two with a 75-inch reach, he was widely regarded as one of the most dangerous undefeated fighters in the sport. His record now sits at 15-1.
Strickland, the reigning middleweight champion, improved to 31-7 with the victory. The 35-year-old from the United States trains out of Xtreme Couture and has built his game around relentless forward pressure and high-volume output, averaging 6.04 significant strikes landed per minute. Standing six-foot-one with a 76-inch reach, "Tarzan" has the frame and pace to make any championship fight competitive over five rounds.
Why it matters
- Chimaev loses his undefeated record and must now rebuild his path back toward title contention
- Strickland successfully defends against the division's top-ranked challenger, reinforcing his standing at 185 pounds
- The split decision result leaves room for a potential rematch conversation at middleweight
- At 32, Chimaev still has time to recover, but the loss reshuffles the divisional picture significantly
