"Rabada has accumulated eight demerit points within a 24-month period automatically leading to a two-match suspension".
The case will overshadow the hosts' preparation for the third Test, which starts in Cape Town on Thursday.
"Aggression can be in what you do, what you say or where you bowl. and that is where I lean to as a cricketer", he said.
"I'm different to KG, I'm a lot more reserved". "I didn't even feel contact in that moment because I was so pumped up".
Proteas captain Faf du Plessis, while acknowledging that the 22-year-old need to be "a bit smarter" when it comes to his wicket-taking celebrations, said Rabada was showing "pure passion" when he got a batsman out. But everything happens in the moment, some bowlers can't hold back those emotions, they're hard to control. It's really competitive out there so your emotions do take over at sometimes.
"As far as the ICC goes, I have no say in what they do, but I've never seen a player banned for two matches before". I just take care of what I do on the field.
Proteas star Rabada - who returned to the No 1 ranking in the ICC Test bowlers list on Tuesday - was suspended for the final two Tests of the gripping four-match series against Australia, at Newlands (starting on March 22) and Wanderers (March 30). "But when I came into global cricket and saw the things that go on, I was taken aback", Ngidi said.
Fast bowler Rabada was found guilty of "inappropriate and deliberate physical contact with a player" after leaning with his shoulder into Steve Smith when he dismissed the Australia captain in the first innings of South Africa's six wicket win in the second test in Port Elizabeth. It was just about assessing the situation and not letting the batsmen get away.
"It was wonderful to see KG bowl like he did and just to be out there when such great cricket was being played, it's good to see. It also means that you know that it's possible for you to do that and it gives you extra motivation to help at the other end, to keep applying pressure and see if you can take one or two wickets too", Ngidi said. The governing body said it will appoint a judicial commissioner in "due course".
