Uzbekistan's Uktamjon Rahmonov has sailed into the last eight of the light welterweight division courtesy of an eight-point victory over an exhausted Yakup Sener.
After a cautious start, Sener exploded into life by unloading a furious barrage of lefts and rights.
Rahmonov did well to absorb most of the punches before responding with a few shots of his own.
The Turk started to look weary in the second round as his exertions began taking their toll. He fell to the floor three times, which caused the referee to issue an eight count.
Rahmonov barely got out of second gear in the final three minutes as he comfortbaly saw out a 16-8 victory.
