Savannah Marshall remains one of Britain’s most compelling boxing stories. Known as the “Silent Assassin,” she has built a reputation for her power, resilience, and quiet determination. In July 2025, Marshall’s name is again on the lips of UK sports fans, following her much-anticipated return to boxing after a stint in mixed martial arts. Her latest bout, a dramatic contest against Shadasia Green in New York, has reignited debate about her legacy and the future of women’s boxing in the UK.
From Hartlepool to the World Stage
Marshall’s journey began in Hartlepool, a town in the North East of England. She started boxing at the age of 12, inspired by a desire to win a trophy like the boys she saw on her street. Despite being the only girl in her local club, she persevered, eventually becoming one of the country’s most decorated amateur boxers. Her amateur career peaked when she won gold at the 2012 World Championships, making her the first British female world champion in boxing.
Her early years were not without struggle. Marshall has spoken about the challenges she faced as a young girl in a male-dominated sport. Many doubted her, but her determination never wavered. This grit would become a hallmark of her career, both inside and outside the ring.
Professional Rise and Rivalries
Marshall turned professional in 2017, signing with Floyd Mayweather Jr. She quickly made her mark, claiming the WBO middleweight title in 2020 with a dominant victory over Hannah Rankin. Her reputation for knockouts grew, with 10 of her 13 wins coming by stoppage. Her aggressive style and technical skill made her a favourite among British boxing fans.
One rivalry, in particular, has defined much of Marshall’s professional narrative: her ongoing saga with American star Claressa Shields. Marshall remains the only boxer to have beaten Shields, a feat she achieved during their amateur days. Their professional rematch in 2022, held at London’s O2 Arena, was historic. It was the first time two female boxers headlined at a major UK venue. Shields won by unanimous decision, but the bout elevated both fighters and women’s boxing as a whole.
Undisputed Champion and a New Challenge
After her defeat to Shields, Marshall moved up to super-middleweight. In July 2023, she defeated Franchón Crews-Dezurn in Manchester to become the undisputed super-middleweight world champion. This victory was a career highlight, as she unified the division and cemented her place among the sport’s elite.
Yet, Marshall’s ambitions did not stop there. She signed with Jake Paul’s Most Valuable Promotions in 2025, signalling her intent to take on new challenges in both boxing and MMA. Her move into mixed martial arts was bold. She made her MMA debut in June 2024, stopping Mirela Vargas in the first round at PFL Europe in Newcastle. Marshall later said that her MMA training made her feel “ten times stronger,” crediting wrestling and jiu-jitsu for her physical transformation.
The Return to Boxing: Marshall vs Green
Marshall’s return to the boxing ring in July 2025 was one of the year’s most anticipated sporting events. She faced Shadasia Green, the WBO super-middleweight champion, in a unification bout at Madison Square Garden. The fight was closely contested, with both women displaying skill and determination.
Marshall started strong, using her jab to control the early rounds. However, Green rallied in the middle rounds, landing a decisive right hook in the fifth that shifted the momentum. The judges delivered a split decision: one scored it 96-93 for Marshall, but the other two gave it to Green, 95-94 and 96-93. Despite a point deduction for Green, Marshall was left frustrated by the result, questioning the fairness of the scoring. She embraced Green after the fight, hinting at the possibility of a rematch.

Reaction and Expert Insight
The split decision loss has sparked debate among fans and experts. Many in the UK boxing community have expressed support for Marshall, praising her performance after two years away from the sport. Marshall herself has been vocal about her disappointment, stating, “All I wanted was a fair fight”. Her supporters argue that her return showcased her resilience and competitive spirit.
Prominent voices in British boxing have highlighted the significance of Marshall’s comeback. Her willingness to step back into boxing at the highest level, after a successful foray into MMA, demonstrates her versatility and dedication. Analysts also note her impressive record: 13 wins, 2 losses, and a knockout ratio of 77%. She has never been stopped, underlining her toughness in the ring.
The Future: What’s Next for Savannah Marshall?
At 34, Marshall continues to inspire a new generation of British fighters. She has spoken about her desire to regain her titles and perhaps secure a long-awaited rematch with Shields. While she admits that a second bout with Shields remains uncertain, her focus is firmly on reclaiming her place at the top of the super-middleweight division.
Marshall’s story is far from over. Her journey from Hartlepool to global stardom, her battles in the ring, and her willingness to take risks have made her a role model in British sport. As women’s boxing continues to grow in popularity, Marshall’s legacy as a pioneer and champion is secure.
