UFC 334 Co-Main Event: Kayla Harrison Vs. Amanda Nunes
A two-time Olympic gold medal winner in judo (2012 and 2016), Kayla Harrison (19-1) made her MMA debut in the 155-pound division with PFL in 2018. Harrison ran over her first six opponents, picking up three submissions, two knockouts, and a decision before winning the women’s lightweight title by defeating Larissa Pacheco by decision.
In November 2020, Harrison defeated Courtney King by TKO in a 145-pound scrap. Shen then moved back to 155 pounds. In 2021, Harrison won the PFL 155-pound tournament with a submission win over Taylor Guardado.
By 2022, Harrison had amassed a 15-0 record. However, her unbeaten ended in the finals of the 2022 PFL lightweight tourney when Pacheco scored a unanimous decision win over Harrison. The ex-champ fought once more for the PFL, beating former UFC fighter Aspen Ladd via decision in November 2023 in a 150-pound catchweight fight.
In January 2024, the UFC announced it had signed Harrison and that her promotional debut would take place in the 135-pound weight class. Harrison impressed in that performance, submitting former UFC women’s bantamweight champion Holly Holm by submission in the second round at UFC 400.
In her next outing, Harrison defeated Ketlen Vieira via unanimous decision.
In June 2025, Harrison captured the UFC women’s bantamweight title with a second-round submission win over Julianna Pena at UFC 316.
After that win, Nunes announced she was coming out of retirement to face Harrison. That fight finally becomes a reality at UFC 334.
If Amanda Nunes is not the best woman to compete in MMA, she is at least in the conversation. Nunes debuted with the UFC in 2013 with a 7-3 record. She opened her career with the promotion with two first-round knockout wins. However, in her third outing under the UFC banner, Nunes fell to Cat Zingano, losing that fight by TKO in the third round.
Nunes would not lose again until December 2021.
During her 12-fight winning streak, Nunes won the bantamweight title and defended it five times, beating notable names Miesha Tate, Ronda Rousey, and Holly Holm by first-round stoppage. Nunes also captured the featherweight belt during that title run, defending it twice. Nunes took ownership of the 145-pound crown with a first-round knockout of Cris Cyborg, who had not tasted defeat in over 13 years.
In a flat and somewhat confusing performance, Nunes lost her 135-pound crown in December 2021, falling to Julianna Pena by second-round submission. In July 2022, Nunes regained the bantamweight belt with a decision win over Pena. She defended the crown against Aldana in July 2023, who replaced the injured Pena in what was to be a trilogy bout. Nunes then retired from active competition as the bantamweight and featherweight champ.
“Double champion forever,” Nunes said after the win. “This is the perfect night to retire.”
The UFC 324 matchup was delayed in mid-January when Harrison underwent surgery to repair herniated discs in her neck.
Nunes will be 38 on fight night, while Harrison will be 36.
