The Olympic soccer tournament is a round-robin format that will take place between September 13-30. Preliminary matches begin September 13, two days before Opening Ceremonies. Matches will take place at Bruce Stadium, the Melbourne Cricket Ground, the Brisbane Cricket Ground, Hindmarsh Stadium and the Sydney Football Stadium. Sixteen men's teams play three games in the first round followed by quarterfinals and two medal rounds. Team's compete in four four-team groups with the top two in each advancing to the quarterfinals. First-round games can end in ties, but the final three rounds will be decided by penalty-kick shootouts. Women will compete in Olympic soccer for the second time, with eight teams making up two four-team groups. After a three-game round-robin competition, the top two teams in each group advance to the semifinals. There are no restrictions on women's teams, but each men's team is limited to players under the age of 23 with three over-age exemptions.
