Featherweight world champion Amanda Serrano has relinquished her WBC title after the organization refused to allow her to compete in bouts under the same set of rules as men’s boxing, with 12 three-minute rounds.
Women’s championship fights are typically scheduled for no more than 10 rounds, with each round lasting two minutes.
Serrano, 35, who had unified the WBA, WBC, IBF, WBO, IBO and Ring Magazine titles, was among the female boxers who launched a campaign in October to have the choice to compete under the same rules as men.
