Demetrious Johnson taught Arman Tsarukyan one clinch lesson, and it ended Mauricio Ruffy's night at UFC 331. Johnson worked with the lightweight contender on cage clinch work, urging him not to just wrestle against the fence but to strip the hand and land a left hook to the body and a right straight. In September 2026, Tsarukyan put it to use, knocking out Ruffy with an explosive elbow at 4:56 of round one. Johnson broke down the finish on YouTube, saying instead of just wrestling, you don't have to wrestle here. Known for relentless pressure and ferocious versatility, Tsarukyan now eyes a dominant, devastating title run against Justin Gaethje in mixed martial arts.
Arman Tsarukyan ended Mauricio Ruffy's night at UFC 331 with an elbow knockout at 4:56 of the first round, a finish that Demetrious Johnson says traces back to a clinch lesson he gave the lightweight contender.
Johnson, who worked with Tsarukyan on cage clinch work, urged him not to simply wrestle against the fence. Instead, he coached Tsarukyan to strip the hand and land a left hook to the body followed by a right straight. After the fight, Johnson broke down the finish on YouTube, pointing to the idea that a fighter does not have to wrestle in that position.
Tsarukyan, 29, is the number two lightweight contender and holds a 24-3 record. The Russian fighter trains out of American Top Team and is known for relentless pressure and versatility. He lands 3.78 significant strikes per minute at 49 percent accuracy and averages 3.25 takedowns per 15 minutes, a blend that makes his clinch work especially dangerous. The win puts him in position to pursue a title run against Justin Gaethje.
Ruffy, 30, entered the bout ranked seventh at lightweight with a 14-3 record. The Brazilian out of The Fighting Nerds stands five-foot-eleven with a 75-inch reach and lands 3.93 significant strikes per minute at 56 percent accuracy. He does not attempt takedowns, which made the exchange against the fence a test of his striking and defense on the inside.
Johnson, 40, is a former flyweight standout with a 27-3-1 record who now fights out of AMC Pankration. His career numbers, including 3.35 takedowns per 15 minutes and 54 percent striking accuracy, reflect the blend of wrestling and precise striking he passed along to Tsarukyan.
