Sri Lanka's Suranga Lakmal and India's Mohammed Shami both vomited on the field as Delhi's notorious smog continued to plague the third Test today.
India's second innings was into its sixth over when Lakmal bent over and threw up before walking off for the ground for the second time in the match.
Shami, who said on Monday that the situation was not as bad as was being reported, was then himself sick in the final session.
