AFP, NEW DELHI: Fast bowler Suranga Lakmal vomited on the ground Tuesday as New Delhi's pollution again took centre stage during the third Test between India and Sri Lanka.

Amid the toxic haze that engulfed the stadium for a fourth day, the Sri Lankan paceman looked sick and pale as he returned to the dressing room after bowling just three overs.

Sri Lanka have protested about the New Delhi air, but the visitors did not immediately comment on the cause of Lakmal's illness.

Coach Nic Pothas said Sri Lankan players had vomited in the dressing room on Sunday because of the pollution.

Lakmal -- who dismissed opener Murali Vijay in the morning session before illness forced him off -- returned to bowl another four overs before lunch on the fourth day of the final Test.

Nine Sri Lankan players apart from the wicketkeeper and the bowler wore face masks as they braved the hazardous air at the Feroz Shah Kotla stadium.
