Gold medal rounds go into sudden death with the winner being the first to score. If no one scores, the referee will determine the winner. All competitors eliminated from gold or silver medal contention will compete in a second bracket to determine the bronze medal. The losing semifinalists will move directly to the semifinal level of the bronze-medal bracket. The remaining competitors will fight to face them in the semifinal round of that bracket.
Opponents earn points with punches to the body or by landing kicks on the head or body.
A 10-second knockout count can begin if any part of a contestant's body other than the foot touches the mat. The competition area is a 12-meter square covered with an elastic mat on a raised platform. The Associated Press contributed to this report. Information are applicable to this site.
