In the group stage, each group was played on a home-and-away round-robin basis. The teams were ranked according to points (3 points for a win, 1 point for a draw, and 0 points for a loss). If tied on points, the following criteria would be used to determine the ranking: 1. Wins; 2. Goal difference; 3. Goals scored; 4. Head-to-head (if the tie is only between two teams). If tied on aggregate, the away goals rule would be used (except if both teams share the same stadium); 5. Fewest red cards; 6. Fewest yellow cards; 7. Draw in the headquarters of the Brazilian Football Confederation (Regulations Article 14).[2]
In the final stage, each tie was played on a home-and-away two-legged basis. If tied on aggregate, the away goals rule would be used. If still tied, extra time would not be played, and the penalty shoot-out would be used to determine the winner (Regulations Article 15).[2]
The matches were played between 16 and 25 September.[3]
Sampaio Corrêa won 2–1 on aggregate and advanced to the semi-finals
Fortaleza won 2–1 on aggregate and advanced to the semi-finals
