Cricket Australia said that it was investigating a heated altercation between David Warner and Quinton de Kock during the first Test in Durban.
The footage, first aired by South African outlet Independent Media, showed the Australian opener pointing and directing a verbal assault at the South African wicketkeeper before getting pulled away by his teammates.
The incident reportedly took place as the players were returning to their dressing rooms at Tea on Day 4.
“CA (Cricket Australia) is aware of reports of an incident between players in Durban,” a Cricket Australia spokesman said in a statement. “CA is working to establish the facts of what has occurred and will not be commenting further until that has been done.”
The Australians had earlier been criticised for their excessive celebration on the dismissal of AB de Villiers. The 34-year-old was run out after being involved in a mix-up with opening batsman Aiden Markram, with Warner and Nathan Lyon effecting the run out.
The vice-captain led the celebrations with his teammates as the off spinner joined them after dropping the ball near the batsman as he ran over.
Former South African captain Graeme Smith was not pleased by the behaviour of the Australian players. He told cricket.com.au in Durban that Lyon would ‘probably say it was unnecessary himself’.
“We’ve got used to Davey (Warner) over the years. I think the less interest you take in him the better,” Smith added.
“He can be a bit of a fool at times. It’s best just to let him be.”
Australia finished the fourth day one wicket short of victory with South Africa on 293 for nine, needing 124 more to win, when bad light ended play at Kingsmead.
