The opening T20 against Bangladesh can't be cancelled at the last minute despite deteriorating air quality in the capital, said BCCI President Sourav Ganguly but dropped hints that North India venues may not be considered for matches after Diwali in future. "It's too late to do anything, because a lot of preparations go into matches like tickets, crowds everything. So it's not possible to cancel things at the last minute. In future, when we schedule, especially in the northern part of India during the winter, we will have to be a little bit more practical. But we have spoken to the Delhi authorities in the last two days. They're expecting the match to go through", said Ganguly.
