One of the most blistering starts to a Test career rattles India in Melbourne, with Virat Kohli appearing to run into Australia debutant Sam Konstas deliberately.

Ricky Ponting said on air: "Virat's walked one whole pitch over to his right and instigated that confrontation. No doubt in my mind whatsoever."

Sam Konstas has become the second-youngest (19 years and 85 days) player for Australia to hit a half-century in Test cricket after Ian Craig. Ian Craig is the youngest (17 years and 240 days) to achieve the milestone.
