Paceman Kagiso Rabada (5-96) ripped the Aussies apart with a fearsome spell taking five wickets in 18 deliveries.
Rabada's physical send off after skipper Steve Smith’s dismissal could cost the fiery 22-year-old his spot in the third and fourth Tests.
Rabada responded to Smith, who had advanced down the wicket and mouthed off at the bowler. Match-referee Jeff Crowe will be forced to take a close look at the incident. Rabada has prevously being fined and is looking at a minimum 2 match ban if found guilty.
There has been plenty of bad blood already in this series with Warner and de Kock squaring off in an ugly spat during the 1st Test a few days back.
2nd Test, March 2018.
