Harper is a three-weight world champion, having previously held titles at junior lightweight and junior middleweight. She won the WBO lightweight title in September 2024 with a unanimous decision victory over Rhiannon Dixon. Harper has had an up-and-down career, suffering a stunning knockout loss to Alycia Baumgardner in 2021, but rebounding to win titles in multiple divisions.

Natalie Zimmermann
Age: 42
Height: 5’6″ (168 cm)
Stance: Orthodox
Professional Rounds: 67
Ranking: WBO #6 Contender
Zimmermann is undefeated but largely untested at the elite level. She transitioned to boxing late in her career, having previously competed in taekwondo and kickboxing, where she won three consecutive German national championships.
Zimmermann has fought exclusively in Europe, with her most recent victories coming against Orsolya Moldovan and Katerina Dvorakova in Spain. This will be her first fight outside of continental Europe, and she will be facing her first opponent with a winning record.
Key Matchups & Fight Analysis
Experience vs. Momentum
Harper has faced world-class opposition, while Zimmermann has yet to fight a top-tier contender. Harper’s experience could be the deciding factor.
Power vs. Precision
Zimmermann has only three knockouts in 13 fights, meaning she will likely need to outbox Harper over 10 rounds. Harper, while not a knockout artist, has respectable power and could wear Zimmermann down.
Home Advantage
Harper will be fighting in her hometown of Doncaster, where she has not competed since 2018. The crowd will be firmly behind her, adding extra motivation.
