Sister of Quinton de Kock calls out David Warner on Twitter

The sledging war between David Warner and Quinton de Kock has reached the next level, with the South African batsman’s sister weighing into the saga via social media.

The Aussie opener has been slapped with a grade two contrary conduct charge which might see him rubbed out of the second Test, while de Kock was hit with a grade one charge for the altercation.

Warner had to be physically restrained by teammates, including Paine, at tea on day four of the first Test after raging at comments allegedly made about his wife by de Kock.

De Kock’s sister has come out swinging at the Australian opener personally calling him out on Twitter.

''Wtf! I'll hurt you,'' she wrote.

The South African team allege Warner referenced de Kock’s sister and mother during a heated exchange on the field.

Other reports allege that Warner called de Kock a ‘bush pig’.

South Africa’s Independent Media claims Warner “led an hour long attack on the field” as de Kock and opener Aiden Markram frustrated the Aussie.

But Australian wicketkeeper Tim Paine has criticised South Africa about the allegations levelled at Warner saying the accusations were “blatantly untue”.

"As I went past de Kock he said what he said and luckily I suppose I was there in between," Australia's keeper declared in Port Elizabeth.

"When you are bringing people's families or wives into it it's unacceptable.

"He (Warner) was certainly extremely fired up and he had every right to be.

"I have never seen him react like he reacted ... he is not the sort of bloke who will whinge about being sledged."
