In a recent grappling session, Khamzat Chimaev showcased his dominance by submitting former UFC flyweight champion Demetrious Johnson in just 47 seconds with a brabo choke. Johnson, who appeared confident at the start, acknowledged the size disadvantage he faced against the reigning UFC middleweight champion. The session was shared on Johnson's Instagram, highlighting their training dynamic. Johnson, known as 'Mighty Mouse,' is set to be inducted into the UFC Hall of Fame during International Fight Week in July 2024. He has also held the 135-pound title in ONE Championship and retired from professional fighting in 2024. Meanwhile, Chimaev is preparing for his first title defense against Sean Strickland at UFC 328 on May 9, 2024, at the Prudential Center in Newark, New Jersey, after winning the middleweight title against Dricus Du Plessis at UFC 319 last August.
