He will now face Mirazizbek Mirzkhalilov of Uzbekistan, who overcame the defending champion, Kairat Yeraliyev of Kazakhstan.

Yeraliyev was under-par throughout the fight, with the referee stopping the contest and handing Mirzkhalilov the victory. 

Lazaro Álvarez of Cuba, the division's top seed, will feature in the other featherweight semi-final.

The three-time world and Pan American Games champion got past Russia's Albert Batyrgaziev 4-1 to silence the partisan crowd.
