Great Britain duo Joshua Buatsi and Pat McCormack make progress on Thursday but Josh Kelly is eliminated in the welterweight division.
Great Britain's Joshua Buatsi has progressed through to the quarter-finals in the light-heavyweight division after stopping Elshod Rasulov.
Buatsi was the underdog to come through his last-16 clash but, as he did in his first contest, he managed to stop his opponent.
Rasulov had been tipped to win a medal but in the final round, he twice hit the canvas before being floored for a third time to leave the referee with little option but to call the bout off.
In the light-welterweight division, Pat McCormack recorded a convincing win over Ablaikhan Zhussupov, despite only winning by split-decision.
Despite one judge ruling the fight a 29-28 victory for the Kazakh, the other two officials ruled in favour of McCormack by a 30-27 scoreline.
However, there was disappointment for welterweight Josh Kelly after he lost by unanimous decision to Daniyar Yeleussinov.
