In the knock-out stage, the 16 teams played a single-elimination tournament, with the teams split between the two zones until the final. Each tie was played on a home-and-away two-legged basis. The away goals rule, extra time (away goals do not apply in extra time) and penalty shoot-out were used to decide the winner if necessary.[1]
The schedule of each round was as follows.[2]
| Round | First leg | Second leg | |
|---|---|---|---|
| Round of 16 | 6–7 May 2014 | 13–14 May 2014 | |
| Quarter-finals | 19–20 August 2014 | 26–27 August 2014 | |
| Semi-finals | 16–17 September 2014 | 30 September–1 October 2014 | |
| Final | 25 October 2014 | 1 November 2014 |
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 second leg.[1] The matchups were determined as follows:
The draw for the quarter-finals was held on 28 May 2014, 16:00 UTC+8, at the AFC House in Kuala Lumpur, Malaysia.[3] The "country protection" rule was not applied, so teams from the same association could be drawn into the same tie.[4]
There was no draw for the semi-finals, with the matchups determined by the quarter-final draw: Winner QF1 vs. Winner QF2 (West Zone) and Winner QF3 vs. Winner QF4 (East Zone), with winners QF2 and QF4 hosting the second leg.
The draw to decide the order of two legs of the final was held after the quarter-final draw.[3]
