American Jamie Mitchell defeated Shannon Courtenay to claim the WBA bantamweight title on a majority judges’ decision after a 10-round fight.
Courtenay, 28, gave up the title after missing the weight for the bout on Friday but a WBA ruling meant a win for Mitchell would allow her to claim the belt.
The Briton only won the world title in her last fight in April, when she beat Australian rival Ebanie Bridges on points.
The judges scored the fight 95-95, 97-93, 96-94 in favour of Mitchell.
“I told you guys I was gonna come out and get the belt and I did exactly what I said I was gonna do,” said Mitchell.
“This changes my life, but a belt doesn’t make me.”
