Football competition
The 2024 CONCACAF Central American Cup knockout stage was played from 24 September to 4 December 2024. A total of eight teams competed in the knockout stage to decide the champions of the 2024 CONCACAF Central American Cup.
Qualified teams
The winners and runners-up of each of the eight groups in the group stage advanced to the quarter-finals.
Teams were seeded 1–8 based on results in the group stage and assigned a position in a fixed bracket. For example, the first semi-final was contested between the winner of the 1 vs. 8 quarter-final and the winner of the 4 vs. 5 quarter-final. For each round, the host of the second leg was determined based on performance in all previous rounds, including the group stage.
Each tie is played on a home-and-away two-legged basis. The home team of the second leg in each tie was determined separately for each round as follows (Regulations Article 12.11):
In the quarter-finals, the group winners hosted the second leg.
In the semi-finals and play-in, the higher-ranked teams based on total points accumulated in the group stage and the quarterfinals hosted the second leg.
In the finals, the higher-ranked team based on total points accumulated in the group stage, quarterfinals and semi-finals will host the second leg.
In the quarter-finals and semi-finals, if tied on aggregate, the away goals rule would be used. If still tied, the penalty shoot-out would be directly used to determine the winners (Regulations Article 12.10.2).
In the play-in and finals, if tied on aggregate, the away goals rule would also be used. If still tied, 30 minutes of extra time would be played but the away goals scored during this time would not serve as a tie-breaking criteria. If still tied after extra time, the penalty shoot-out would be used to determine the winner (Regulations Article 12.10.3).
