The elimination phase of the 2014 Copa Sudamericana was played from August 19 to September 24, 2014. A total of 46 teams competed in the elimination phase.[1]
The draw of the tournament was held on May 20, 2014, 12:00 UTC−3, at the Sheraton Hotel in Buenos Aires, Argentina.[2]
Excluding the defending champion (entering in the round of 16), the other 46 teams were divided into four zones:
The draw mechanism was as follows:[1]
The following was the seeding of the 46 teams entered into the first stage and second stage draw:
| Teams entering in the first stage | Teams entering in the second stage | ||||||
|---|---|---|---|---|---|---|---|
| width=300 | South Zone (16 teams) | width=300 | North Zone (16 teams) | width=300 | Argentina Zone (6 teams) | width=300 | Brazil Zone (8 teams) |
In the elimination phase, each tie was played on a home-and-away two-legged basis. If tied on aggregate, the away goals rule was used. If still tied, the penalty shoot-out was used to determine the winner (no extra time was played). The 15 winners of the second stage (three from Argentina Zone, four from Brazil Zone, eight from ties between South Zone and North Zone) advanced to the round of 16 to join the defending champion (Lanús).[1]
The first legs were played on August 19–21, and the second legs were played on August 26–28, 2014.[3]
