The most personal grudge match in recent UFC history reached its boiling point on May 9, 2026, when undefeated middleweight champion Khamzat "Borz" Chimaev (15-0) met former titleholder Sean Strickland (30-7) in the main event of UFC 328 at the Prudential Center in Newark, New Jersey. What began as a friendly training partnership in 2022 had devolved into one of the most toxic and violent rivalries the sport has seen, complete with death threats, personal attacks about family trauma, a physical altercation at the pre-fight press conference, and a weigh-in controversy that has left the MMA world demanding reform.
From Training Partners to Mortal Enemies: The Origins of the Feud
The story of Chimaev vs. Strickland began innocently enough in 2022. Chimaev, then a welterweight contender preparing for a fight with Nate Diaz at UFC 279, visited Las Vegas alongside his friend Darren Till to train at Xtreme Couture, Strickland's home gym. At the time, the two fighters were competing in different weight classes and appeared friendly. "Be nice," Strickland told Chimaev during those early sessions. "Khamzat, understand you're better than everybody, so just don't hurt people."
Those sparring sessions would become the foundation of their rivalry. Both fighters have insisted they got the better of the exchanges, with no video evidence ever released to settle the debate. "He said he beat me in sparring," Chimaev said in July 2024. "But there were a lot of guys around who saw me choking him and beating him up. It was even recorded on camera."
Timeline: How the Beef Escalated Into a Full-Blown War
Fall 2023 - Title Contentions: After Chimaev scored a close majority decision win over Kamaru Usman at UFC 294, Strickland — then the UFC middleweight champion — dismissed the victory and argued Chimaev hadn't earned a title shot. "The only thing I like about Chimaev is that he sells fights," Strickland said. "He doesn't f***ing deserve it, but here we are."
February 2025 - The Turning Point: The feud turned deeply personal when Chimaev mocked Strickland's appearance on Theo Von's podcast, where Strickland discussed his abusive upbringing. "Why are you baby crying all the time?" Chimaev tweeted alongside a photo of Strickland with his father. "Father didn't give you love or he showed his love to you too much?"
Strickland's response was nuclear. He went after Chimaev's relationship with Chechen leader Ramzan Kadyrov, a dictator with a notorious human rights record. "I guarantee this little w—re sucked off Kadyrov," Strickland fired back. "Obviously not good enough because you had to flee your country." This exchange set the tone for everything that followed.
August 2025 - Chimaev Wins the Title: At UFC 319, Chimaev defeated Dricus du Plessis via unanimous decision to claim the UFC middleweight championship. Rather than celebrating, Chimaev immediately turned his attention to Strickland, and the rivalry only intensified.
February 2026 - The Inactive Champion Narrative: Strickland trashed Chimaev for failing to defend his belt in the nine months since winning it. "You brought a guy in that fights once a year who's like Madonna," Strickland said. "The guy doesn't need to fight. He's best friends with a warlord."
Fight Week Explodes: The Kicking Incident and Weigh-In Controversy
The tension reached a fever pitch during UFC 328 fight week. At the pre-fight press conference, with armed police and UFC security present, Chimaev and Strickland faced off for photos. In a moment that shocked the combat sports world, Chimaev kicked Strickland below the belt, nearly inciting an all-out brawl. "Lines were certainly crossed," wrote MMA Mania's Dan Hiergesell. "Things have become so bad that Strickland even threatened to shoot the UFC champion and his team earlier this week."
UFC CEO Dana White, however, was unbothered by the mayhem. "It doesn't scare me," White told TMZ on the Friday before the fight. "It's been a minute since I've had a fight that's had this much heat on it. It's exciting."
The weigh-in added another layer of controversy. Strickland accused Chimaev of not actually making weight, claiming the scales were rigged. Reports emerged that Chimaev had cut a staggering 46 pounds (21 kilograms) for the fight, leading to his gaunt, depleted appearance on the scale. Dustin Poirier was among the UFC fighters calling for digital scales to prevent future controversies. "As soon as he steps on the scale, they say 185. It didn't look right," Poirier said.
The Fight: Styles Make Fights in the Ultimate Grudge Match
Inside the Octagon, the fight presented a classic clash of styles. Chimaev, a Chechen-born grappling phenom who now fights out of the UAE, entered as a massive -600 favorite. His game plan was never in question: take the fight to the ground and impose his will with overwhelming wrestling pressure, the same approach that earned him the title against du Plessis and produced six submission wins in his career.
Strickland, a +425 underdog, is known for his high-volume jab, defensive wrestling, and incredible durability. His path to victory centered on surviving the early onslaught, making Chimaev work, and taking over in the later rounds with his superior cardio. As MMA Fighting's Jed Meshew broke it down: "Big picture, the plan for Strickland is pretty simple: survive early, make Chimaev work, pile on jabs and teeps to start draining Chimaev's gas tank, and take over in the later rounds with volume."
The Bigger Picture: What This Means for the Middleweight Division
Regardless of the outcome, UFC 328 represented a pivotal moment for the middleweight division. Chimaev, at just 32 years old, has been touted as a potential generational talent since his UFC debut, drawing comparisons to a young Khabib Nurmagomedov. A win over a former champion like Strickland would cement his reign and open up intriguing possibilities, including a potential super fight.
Strickland, 35, has led one of the strangest careers in recent memory. A former champion who lost the belt to du Plessis, he has consistently defied expectations and pulled off upset wins when counted out. His journey from a troubled childhood to the pinnacle of combat sports has made him a fan favorite, and his willingness to engage in the ugliest of trash talk has made him one of the sport's most polarizing figures.
Analyst Rashad Evans highlighted what makes Chimaev so dangerous: "He has not fought since August 2025, but his overwhelming physical dominance is something we haven't seen in the division. He's a different breed of grappler."
Where Things Stand Now: The Aftermath of UFC 328
The fallout from UFC 328 extends beyond the cage. The weigh-in controversy has sparked a broader conversation about UFC's weight-cutting protocols, with multiple fighters calling for the promotion to adopt digital scales for transparency. Arman Tsarukyan revealed that Chimaev had to cut 21 kilograms for the fight, raising questions about the safety and fairness of extreme weight cuts.
The personal nature of the rivalry has also divided the MMA community. While some praise the raw emotion and promotional value, others worry about the line between selling a fight and genuine endangerment. Strickland's threat to shoot Chimaev and his team, combined with Chimaev's physical attack during the staredown, pushed the boundaries of what is acceptable in fight promotion.
What Happens Next: The Road Ahead for Both Fighters
For Chimaev, the future is bright and full of possibilities. A successful title defense against a former champion like Strickland opens the door to fights against top contenders like Nassourdine Imavov, or perhaps a move up to light heavyweight for super fights. His undefeated record and dominant style make him one of the UFC's most valuable stars.
For Strickland, the road is less certain but never boring. Even in defeat, his ability to generate interest and sell fights ensures he will remain a prominent figure in the division. His resilience and durability mean he is likely just one or two wins away from another title opportunity, and his willingness to fight anyone ensures he will continue to be a fixture in main events.
