Unbeaten boxer Georgia O’Connor has died at age 25, just weeks after marrying her longtime boyfriend.

“A true warrior inside and outside,” her promotion firm, Boxxer, wrote on X Thursday. “The boxing community has lost a talented, courageous and determined young woman far too soon.”

“Georgia was an inspirational person and one I’ll never forget,” CEO Ben Shalom added.

In January, the British fighter said she had been diagnosed with metastatic cancer.

She was a Commonwealth Youth Games champion and Youth World Championships silver medalist before embarking on a professional career in 2021. She won all three of her fights, her last one taking place in 2022.
