Star Indian batter Virat Kohli and Australian youngster Sam Konstas were on Thursday involved in a physical altercation as tempers flared on the first day of the fourth Test here but the 19-year-old home debutant played down the incident.

The brief showdown took place after the completion of the 10th over of the Australian innings when the players were crossing over. Kohli and Konstas bumped shoulders while moving across the pitch.
