2015 AFC Cup knockout stage
The 2015 AFC Cup knockout stage was played from 26 May to 31 October 2015. A total of 16 teams competed in the knockout stage to decide the champions of the 2015 AFC Cup.
The winners and runners-up of each of the eight groups in the group stage qualified for the knockout stage. Both West Zone and East Zone had eight teams qualified.
In the knockout stage, the 16 teams played a single-elimination tournament. In the quarter-finals and semi-finals, each tie was played on a home-and-away two-legged basis, while in the round of 16 and final, each tie was played as a single match. The away goals rule (for two-legged ties), extra time (away goals would not apply in extra time) and penalty shoot-out were used to decide the winner if necessary.
The schedule of each round was as follows.
In the round of 16, the winners of one group played the runners-up of another group in the same zone, with the group winners hosting the match. The matchups were determined as follows:
The draw for the quarter-finals was held on 18 June 2015, 15:00 UTC+8, at the Grand Millennium Hotel in Kuala Lumpur, Malaysia. Teams from different zones could be drawn into the same tie, and there was no seeding or country protection, so teams from the same association could be drawn into the same tie.
In the semi-finals, the matchups were determined by the quarter-final draw: Winner QF1 vs. Winner QF2 and Winner QF3 vs. Winner QF4, with winners QF2 and QF4 hosting the second leg.
In the final, the host team was determined by a draw, held after the quarter-final draw.
