The competition consists of a single-elimination tournament, with a repechage used to determine the winner of two bronze medals.

Each wrestler who loses to one of the two finalists moves into the repechage, culminating in a pair of bronze medal matches featuring the semifinal losers each facing the remaining repechage opponent from their half of the bracket.
