Caroline Dubois made her professional debut in 2022

Caroline Dubois floored and bloodied Terri Harper before outpointing her British rival to become the unified lightweight world champion at London's Olympia.

After a dull first half of the contest, Dubois dropped Harper with a classy jab and left hook in the sixth round.

Doncaster's Harper, who suffered a nasty cut after a clash of heads in the eighth, showed great spirit to continue throwing until the final round.

The judges scored the fight 98-91, 97-92 and 98-91 to Dubois, who adds Harper's WBO belt to her WBC title.
