Former world silver-winner Sonia Lather (57kg) entered the semi-finals to be assured of a medal but defending champion Nikhat Zareen (51kg) bowed out of the Strandja Memorial Boxing Tournament in Sofia, Bulgaria on Thursday.
Lather, a two-time Asian silver-medallist, clinched a 3-2 triumph over Ireland's Michaela Walsh in a tight contest.
However, former junior world champion Zareen was beaten by a similar margin in her last-eight clash against American Christina Cruz.
Zareen had claimed a gold medal at the previous edition of the event, which is in its 71st edition this year.
Among the men, four-time Asian silver medallist Shiva Thapa (63kg), Commonwealth Games bronze-winner Mohammed Hussamuddin (57kg) and Duryodhan Singh Negi (69kg) will compete in the quarter-finals later tonight.
