A Test match between India and Sri Lanka was halted due to smog in Delhi.
The Indian capital has been suffering from severe air pollution issues for several weeks, causing the Sri Lankan players to take to the field wearing masks for the third Test.
The visitors had just 10 men on the pitch at one point, with Lahiru Gamage and fellow bowler Suranga Lakmal leaving the field during the afternoon session.
The umpires became so concerned they consulted doctors and physiotherapists before resuming.
India declared their first innings on 536-7, with captain Virat Kohli scoring a career-best 243.
In reply, Sri Lanka reached 131-3 at the end of the second day. India lead the series 1-0.
