Undisputed featherweight world champion Amanda Serrano has announced she is relinquishing her WBC title after the governing body refused to sanction fights of 12 three-minute rounds.
The Puerto Rican retained her WBO, WBA and IBF belts in October with victory over Danila Ramos in a contest fought over that length.
However, her WBC title was not on the line because the organisation did not endorse the format.
Women’s fights are typically fought over 10 two-minute rounds.
Serrano wrote on Instagram: “Moving forward if a sanctioning body doesn’t want to give me and my fellow fighters the choice to fight the same as the men, then I will not be fighting for that sanctioning body.
“The WBC has refused to evolve the sport for equality. So I am relinquishing their title.
“Thank You to the sanctioning bodies who have evolved for Equality!”
