Despite smog, why wasn't IND Vs BAN match cancelled?

There were news stories that the series opener of the 3-match T20 international series between India and Bangladesh would be called off owing to poor visibility due to the dense smog which looms large over the skies across the national capital region since morning. But it did not happen so. The teams reached the stadium and the match is underway. But why wasn't the match cancelled? Is money more important for BCCI than a player's health?
