He captured the UFC Lightweight Championship in 2021, defeating Michael Chandler, and though he later lost the title on the scale due to missing weight, he remains a top contender and one of the most exciting and dynamic fighters in the division. His aggressive style and relentless pursuit of finishes have made him a fan favorite.
