The fourth T20 international between India and South Africa in Lucknow on Wednesday was called off without a ball being bowled due to excessive fog at the Ekana Cricket Stadium.
The umpires made field inspections every 30 minutes, only to find no improvement in the visibility as a dense fog hung in the air and enveloped the floodlights.
The match was called off before the toss could take place.
India lead the five-match series 2-1. The final T20 game will take place in Ahmedabad on Friday.
