Watch: David Warner and De Kock row shows ugly side of cricket

The Australian cricket team is on tour to South Africa for a four-test match series. Currently, Aussies lead by 2-0 and looking forward to clinching the series.

In just one game, a lot of things has happened already and the ugly side of cricket is visible. Recently, Australian off-spinner Nathan Lyon was booked by ICC for disrespecting former South African skipper AB de Villiers.

Now, another incident which was escalated after de Villiers' run out incident when both the teams were returning to their dressing rooms during the tea break on the fourth day of the first Test.

A leaked CCTV footage showed David Warner apparently turning on De Kock as the players walked up a narrow staircase. Their captains said personal insults were at the root of a row between Australia's David Warner and South Africa's Quinton de Kock.

Steve Smith: "What was said and done during that interval was regrettable on both sides."

Faf du Plessis: "From what I've heard there was a lot of personal stuff being said, to and from."

The incident is in the hands of match referee Jeff Crowe, with no immediate clarity about when a decision could be expected.
