France's Nordine Oubaali has beaten Rau'Shee Warren to leave the United States with just one fighter remaining in the Olympics.
Warren looked sharp and was busy in the opening round, catching Oubaali with a few nice counters to take a 9-6 lead.
The Frenchman attacked with more purpose in the second, but found Warren a difficult target to hit.
However, a great left hook found its target and seemed to turn the tide of the bout.
The gap between then was just a single point as they entered the final three minutes and the impetus was firmly with Oubaali, who wobbled Warren with a crashing right hand.
Oubaali was in the ascendancy in the final seconds and another crisp shot seemed to confirm his victory.
The judges agreed and handed him a 19-18 decision.
