Heavyweight boxer Nupur Sheoran assured India of its first medal at the World Boxing Championships as she defeated Oltinoy Sotimboeva of Uzbekistan to reach the semi-finals of the women’s +80kg category here on Wednesday.

Granddaughter of legendary boxer Hawa Singh, the 26-year-old Nupur, who entered the competition directly in the quarterfinals, overcame a scrappy contest to beat Uzbek 4-1 and secure at least a bronze medal. The +80kg, which is a non Olympic weight category, features just 10 boxers in the ongoing competition.
