There were even reports about the match possibly getting cancelled due to visibility issues. However, the match went on as usual due to some miracle. The fact of the matter is that the AQI in Delhi had reached levels that weren't ideal for a game of cricket.

Speaking to reporters BCCI President Sourav Ganguly said: 

We have spoken to Delhi authorities over the last two days, they are expecting the match to go through, we couldn’t cancel it at last minute. 

He added:

Post-Diwali is a difficult time in the north because winter sets in and there is a lot of smoke & dust. In the future, when we schedule, especially in the northern part of India in the winter we will have to be a little more practical.
