LIVERPOOL: Heavyweight boxer Nupur Sheoran assured India of its first medal at the ongoing World Boxing Championships when she defeated Oltinoy Sotimboeva of Uzbekistan to enter the semi-final round on Wednesday.

Competing in her first bout of the championships, Nupur prevailed 4-1 over her opponent to make the last four stage of the +80kg event, which features only 10 boxers.

With the win, Nupur is assured of at least a bronze medal.
