An Italian boxer abandoned her bout at the Paris Olympics after only 46 seconds on Thursday, refusing to continue after taking a heavy punch from an Algerian opponent who had been disqualified from last year’s world championships over questions about her eligibility to compete in women’s sports.

Imane Khelif, 25, was permitted to compete at the Olympics even though she had been barred last year after boxing officials said she did not meet eligibility requirements to compete in a women’s event. Another athlete also barred from last year’s world championships under similar circumstances, Lin Yu-ting, has also been cleared to fight in Paris.
