Pollution stopped play in the third Test between India and Sri Lanka, and visiting coach Nic Pothas said the smog was so extreme that his players -- who took the extraordinary step of wearing face masks -- were "coming off the field and vomiting". The match was halted for around 20 minutes at the Feroz Shah Kotla stadium as Sri Lankan fielders complained of health troubles and the umpires consulted the match referee and team doctors.
