Kayla Harrison: Olympic Gold, UFC Champion, Mother

Kayla Harrison has a habit of making history look simple. She’s the first American to win Olympic gold in judo, and she did it twice — in 2012 and 2016. Now she’s a UFC bantamweight champion and a single mom by adoption. This is the story of a fighter who keeps redefining resilience.

Eight facts capture the key dimensions of Kayla Harrison’s career and life, from her Olympic roots to her current role as a UFC champion and mother.

What happened to Kayla Harrison in the UFC?

UFC 324 fight cancellation due to neck injury

In January 2026, Kayla Harrison withdrew from the co-main event of UFC 324 because of a neck injury. The injury required surgery to address herniated discs in her neck, according to Reuters (international news agency). Harrison issued a statement through Sportsnet (Canadian sports broadcaster) saying she had neck surgery in New York City and called the recovery “the road back starts now.”

Impact on Amanda Nunes fight

The withdrawal also shelved a highly anticipated matchup against former champion Amanda Nunes, which was expected to headline the card. The UFC has not announced a rescheduled date, leaving the status of that fight uncertain. Harrison’s neck surgery recovery timeline will determine when she can return to the Octagon.

The implication: Harrison’s title reign is on hold, and the bantamweight division is seeing a shake-up just months after she claimed the belt.

How did Kayla Harrison get her kids?

Adoption of her sister’s children

Kayla Harrison adopted her sister’s two children, Kyla and Emery, after a family tragedy. Her sister struggled with addiction, and after Harrison’s mother suffered a stroke and her stepfather died suddenly in May 2020, she stepped in to raise the children. Raise Magazine (parenting publication) reported that Harrison’s stepfather Bob had been caring for the children before his death. Harrison officially adopted Kyla first, followed by Emery, in October 2021, according to the Associated Press (news wire service).

Becoming a single mother through adoption

Harrison described the adoption as “the best day of my life, by far,” in an interview with the AP. She now raises Kyla and Emery as a single mother while balancing her MMA career. In a BBC Sport (public broadcaster) profile, she opened up about the emotional journey of becoming a parent and how it changed her perspective on fighting.

What this means: Harrison’s identity as a mother is as central to her story as her medals. The adoption story adds a layer of resilience that few athletes can match.

Is Kayla Harrison a single mom?

Her family structure

Yes, Kayla Harrison is a single mother. She adopted her sister’s two children and raises them alone. In interviews, she has referred to herself as a “cool mom, a single mom, a fighter.” The Associated Press confirmed that she is the sole legal guardian of Kyla and Emery.

How she balances motherhood and MMA

Harrison has spoken openly about bringing her children to training camps and making sure they are part of her journey. She told BBC Sport that being a mother gives her a different kind of strength in the cage. “I’m fighting for them now,” she said. The trade-off: she has to manage her training schedule around school runs and bedtime, but she says it keeps her grounded.

The catch: Harrison’s dual role as elite athlete and sole parent demands constant trade-offs, but she credits motherhood with sharpening her focus inside the cage.

What gender is Kayla Harrison?

Clarification on gender identity

Kayla Harrison is female. She competes in the UFC women’s bantamweight division, which is exclusively for female athletes. Official UFC roster listings and her personal website identify her as a woman. There is no ambiguity in any official records or medical documentation. The question may arise from her muscular build and dominant fighting style, but Harrison has always competed as a female athlete.

What is Kayla Harrison’s MMA record?

Professional record breakdown

Kayla Harrison’s professional MMA record stands at 19 wins and 1 loss, according to her official website. Of those 19 wins, 6 came by knockout or TKO, and 8 by submission. She holds the UFC women’s bantamweight championship, which she won in 2025 by defeating Julianna Peña, as reported by Reuters.

Notable wins and losses

Before joining the UFC, Harrison was a two-time PFL women’s lightweight champion. Her only loss came in 2023 to Larissa Pacheco in the PFL. She avenged that loss later in the same season. Since signing with the UFC in 2024, she has been undefeated in the promotion. Sportsnet noted that she became the second Olympic champion to win a UFC title, after Henry Cejudo.

The pattern: Harrison’s ability to avenge her only loss and then dominate a new promotion underscores her adaptability across combat sports.

“I’m a cool mom, I’m a single mom, I’m a fighter.”

— Kayla Harrison, via Instagram interview (BBC Sport)

After neck surgery, Harrison posted on social media that “the road back starts now,” as reported by Sportsnet (Canadian sports broadcaster).

Harrison called the day her adoption was finalized “the best day of my life, by far,” according to an interview with the Associated Press (news wire service).

For Kayla Harrison, the road back from neck surgery is clear: recover fully, then reclaim her place as one of the most dominant champions in MMA history. The bantamweight division is waiting, but so are her kids. She’s used to balancing both.

Her path to UFC gold was shaped by the same resilience that defined Kayla Harrisons journey as a single mother and her decision to adopt her sister’s children.
