Juliana Miller Record: 5-4-0

Grappling pedigree and TUF run

Before and during her rise, Miller built a reputation on the submission-grappling scene that hardened her ground game. She edged Fatima Kline on escape time at Submissions on the Shore in 2020, submitted Montserrat Rendon at Combat Jiu-Jitsu Mexico in 2021, and outlasted decorated grappler Beatriz Mesquita in EBI overtime at Medusa 1 that same year. That grappling foundation carried straight into the cage.

UFC tenure

Miller capped her TUF 30 campaign with the tournament final in August 2022, stopping Brogan Walker by third-round TKO with punches and elbows to take the title and her roster spot. The transition to the elite level proved demanding: she dropped a unanimous decision to Veronica Hardy at UFC 286 in March 2023, then suffered a first-round TKO loss to Luana Santos that August before a shoulder injury and surgery sidelined her. She returned in May 2025 to score a much-needed unanimous-decision win over Ivana Petrović, only to drop a unanimous decision to Carli Judice in February 2026.

Fighting style

Miller is fundamentally a grappler, and her finish breakdown reflects it: two of her four professional wins have come by submission and one by knockout, against a single decision. Schooled in the 10th Planet no-gi system, she looks to drag fights to the mat, where her control and submission entries are her best weapons, and her length helps her chain attacks. The honest gap in her UFC results has been on the feet and in close decisions — three of her four losses have come by decision and one by knockout — pointing to a striking game and takedown setup that still need to catch up to her grappling ceiling.

Career highlights

• TUF 30 flyweight winner — ran through the season and stopped Brogan Walker by third-round TKO in the 2022 final to claim her UFC contract.
• Submission grappling resume — beat world-class competition on the grappling circuit, including a 2021 EBI-overtime win over Beatriz Mesquita at Medusa 1.
• Resilient comeback — returned from shoulder surgery and a lengthy layoff to win a 2025 decision over Ivana Petrović, snapping a two-fight skid.
