Namibia's Mujandjae Kasuto has booked his place in the next round of the middleweight class with a tight victory over Sobirdzhon Nazarov of Tajikistan.
The early exchanges showed that the fight would be a close contest, and the judges were unable to separate the pair after the first round.
Kasuto managed to get his nose in front after the second round and held a one-point advantage heading into the decider.
Nazarov boxed better at the start of the final round, but could not sustain his momentum and eventually lost by an 11-8 scoreline.
