India vs Sri Lanka 2017: 3rd Test, day 4, 5 things we learnt from the day

#5 Pollution continues to hog limelight

Nine Sri Lankan players wore masks on the fourth day while fielding

Hazardous conditions at the Feroz Shah Kotla continued to be under the microscope as Suranga Lakmal vomited on the ground on Tuesday. Nic Pothas had also clarified that players had been throwing up in the dressing room as well. Sri Lanka even protested against the match still being played despite the alarming level of pollution in the Indian capital.

The US Embassy lists air quality in Delhi at 398, which is fifteen times more than WHO's permissible limit. With face masks on and bizarre playing conditions owing to the smog, the Delhi Test has become more than just cricket. The debate is likely to continue way after the match gets over with BCCI taking minimal steps to avoid the farce that manifested during the Test.
