Brendan Allen

Brendan Cody Allen is an American professional mixed martial artist competing in the middleweight division of the Ultimate Fighting Championship. Born on December 28, 1995, in Beaufort, South Carolina, he has built a reputation as one of the most technically sound grapplers in the sport's 185-pound class. Known professionally by his nickname "All In," Allen fights out of Covington, Louisiana, where he trains at Kill Cliff FC.

As of September 2026, he holds the number five ranking in the Meta UFC middleweight standings. His career is defined by relentless pressure and a high proficiency in Brazilian Jiu-Jitsu, often resulting in submissions or dominant decision victories. He turned professional in 2015 and made his UFC debut in 2019 after capturing the Legacy Fighting Alliance Middleweight Championship. [edit]

Brendan Cody Allen was born in Beaufort, South Carolina, where he spent his early years developing a foundation in combat sports. Before stepping into the professional cage, he was a standout wrestler who honed his skills during his high school years in South Carolina. While specific details about his collegiate wrestling career remain less publicized than his MMA achievements, his time in amateur circuits provided the necessary grappling base for his future success.

Allen eventually relocated to Covington, Louisiana, which became his permanent home and training ground. The transition from amateur competition to professional fighting marked a pivotal shift in his life. He turned pro in 2015, immediately entering the regional circuit to build a resume that would catch the eye of major promotions. His breakthrough moment arrived when he captured the Legacy Fighting Alliance Middleweight Championship, a title that served as the definitive springboard for his recruitment into the Ultimate Fighting Championship.

After securing the LFA Middleweight Championship in 2018, Allen signed with the UFC and made his promotional debut in 2019. He quickly established himself as a main event regular rather than a journeyman filler, showcasing a fighting style that blends technical striking with suffocating grappling pressure. Between 2020 and 2022, he compiled a string of wins against ranked opponents, solidifying his status as a consistent contender in one of the organization's most competitive divisions.

His momentum continued through 2023 and 2024, with significant victories that placed him firmly in the top ten of the world rankings. By 2025, Allen had refined his skills against elite middleweights, proving he could handle the highest level of competition. A notable highlight occurred on August 31, 2026, when he submitted a member of Team Khabib with a slick heel hook at ACBJJ 22, demonstrating his grappling dominance outside the Octagon. This performance led to his booking for the main event of UFC Vegas 122 against Christian Leroy Duncan on October 1, 2026, marking his fifth appearance headlining a UFC card. [edit]
