Early Life & Education

Kayla Harrison was born on July 2, 1990, in Middletown, Ohio, to Jeannie Yazell, a judo black belt, and Kenny Harrison Jr. . She began judo training at age six under her mother’s guidance, quickly showing prodigious talent in the sport .

Sexual Abuse by Coach Daniel Doyle

When Harrison was 13 years old, her judo coach, Daniel Doyle, began sexually abusing her. The abuse occurred over three years, with some incidents taking place during overseas tournament travel . Harrison later described the grooming process: “I moved to the club when I was eight years old. From a young age, I had a very keen drive to please people. I wanted everyone to love me. I wanted to be the center of attention. You know, Daniel definitely fed off that” .

Her mother discovered the abuse through one of Kayla’s friends and reported Doyle to police. In November 2007, Doyle pleaded guilty to “engaging in illicit sexual conduct in a foreign place” and was sentenced to 10 years in federal prison .

The trauma nearly destroyed her. “I hated judo,” Harrison recalled. “I hated the Pedros. I didn’t want to be the strong girl. I didn’t want to be the golden girl, I didn’t want to be the one who overcame everything” . At her lowest point, she was found on the roof of a two-story apartment, contemplating suicide .

The Pedro Rescue

At 16, Harrison moved to Wakefield, Massachusetts, to train under Jimmy Pedro Jr. and his father “Big Jim,” who became her coaches and surrogate family . Pedro Jr., a two-time Olympic bronze medalist, described her arrival: “She was not in a good state of mind… She was somebody who had no self-esteem. She didn’t know, really, right from wrong” . The Pedros and her teammates slowly rebuilt her confidence, pulling her “off the mat when she was crying and wanted to quit” .

Career Journey

Judo Dominance and Olympic Glory (2004–2016)

Harrison’s competitive judo career was historic:

  • 2004 Athens Olympics: Youngest judoka to qualify, at age 17 (lost first match)
  • 2008 Beijing Olympics: Did not qualify
  • 2010 World Championships: Won gold in the 78 kg weight class
  • 2012 London Olympics: Became the first American to win Olympic gold in judo, defeating Great Britain’s Gemma Gibbons
  • 2016 Rio Olympics: Defended her title, becoming the first American to win two Olympic gold medals in judo

After Rio, she retired from competitive judo and transitioned to MMA.

Professional Fighters League (2018–2023)

Harrison made her MMA debut in June 2018 with the Professional Fighters League (PFL). She dominated the women’s lightweight division:

  • 2019 PFL Season: Won the championship and $1 million prize
  • 2021 PFL Season: Won the championship and $1 million prize again
  • 2022 PFL Season: Suffered her first professional loss to Larissa Pacheco by unanimous decision in the championship final, ending her 15-0 streak

UFC Arrival and Bantamweight Title (2024–Present)

Harrison signed with the UFC and made her debut at UFC 300 on April 13, 2024, submitting former champion Holly Holm with a rear-naked choke in the second round . She followed up with a unanimous decision win over Ketlen Vieira at UFC 307 (October 2024) .

On June 7, 2025, at UFC 316, Harrison captured the UFC Women’s Bantamweight Championship by submitting Julianna Peña with a kimura in the second round .

UFC 324 Postponement and Neck Surgery

In January 2026, Harrison was scheduled to defend her title against returning legend Amanda Nunes at UFC 324. However, she was forced to withdraw due to herniated discs in her neck requiring surgery . UFC CEO Dana White confirmed the promotion plans to re-book the matchup later in 2026 . Nunes stated she would wait for Harrison, saying, “I know she’ll be able to get better and I’m going to wait for her. This is the fight that I want” .

Personal Life

Adoption of Niece and Nephew

In 2019, Harrison’s mother suffered a stroke. She had been the custodian of Harrison’s sister’s two children, Kyla and Emery, as her sister was unfit to raise them. Then in May 2020, Harrison’s stepfather, Bob, suddenly died .

Harrison stepped up and became the legal guardian of her niece and nephew. “I became the guardian of my niece and nephew,” she told MMA Junkie. “I love them so much, and I so badly want to get it right for them. I thought I wanted to be the best [fighter] in the world so bad. Take that feeling and multiply it by a hundred thousand. That’s how I feel for these kids” .

Relationships and Dating History

Harrison has had a complicated romantic history that has shaped her current boundaries:

  • Aaron Handy (engaged, ~2012): A fellow judo black belt who later became a firefighter. Harrison reportedly considered following him into firefighting. The engagement eventually ended .
  • Anthony Rocco Martin (~2019–2021): A former UFC fighter with an 18-6 record whom Harrison dated after joining American Top Team. The relationship turned troubled. In September 2021, Harrison filed for a restraining order in Broward County, Florida, which was renewed twice before she dismissed it in March 2022. In December 2022, police responded to a rental property in Lee County where Harrison was reportedly in distress. Another report followed in February 2023, which remains under investigation .

Harrison has since established a firm rule: “I have a hard rule now—no more fighters. I’m not allowed to date fighters” . She now seeks a partner who is “family-oriented” and “chill,” explaining, “I don’t need you, but I want you” .

Controversies

Restraining Order and Domestic Issues

Harrison’s legal filings against Anthony Rocco Martin and subsequent police incidents drew media attention, though she has never publicly detailed the specifics. The incidents led to her “no dating fighters” rule and reinforced her focus on her children and career .

Tyrone Spong Allegations

In July 2025, Harrison accused boxer Tyrone Spong of stalking her and derailing her fight career, claiming their friendship turned romantic in late 2021, two months after her first restraining order against Martin .
