Match referee Jeff Crowe found Rabada was responsible for making "inappropriate and deliberate physical contact" with Smith in Port Elizabeth.
"Whether KG is playing in the third Test or not‚ it's out of our hands, and hopefully we can put this all behind us and carry on playing cricket".
He was hit with three demerit points as punishment for the incident, taking him to eight in total within a two-year period.
Opener Dean Elgar, though, insists the Proteas are not focusing on what the outcome is.
Assessing the South African attack, Bancroft said that the possible recall of Morne Morkel would pose a very different challenge to Rabada. "Having him in the side is massive for us, massive for the game and massive for the format, because KG is such aspecial cricketer", Elgar said.
"I've been on the receiving end but I've also given it out‚ in all the right measurements".
With a lot of the talk in the first two Tests about off-field matters, Elgar was happy to have a break from the game after back to back Tests in Durban and Port Elizabeth.
It was these sorts of contributions - and even bigger - that Elgar consistently produced in 2017, when he finished as the world's third-highest Test run-scorer with 1 128 at an average of 53.71.
However, Rabada later appealed against the guilty verdict handed to him by the ICC for breaching their code of conduct in a last-ditch bid to be able to play in the rest of the gripping series against Australia. "I think he'll take it in his stride". He's quite a relaxed human being‚ but on the field he's as competitive as anyone else.
With Kagiso Rabada's fate hanging in the balance and Dale Steyn continuing to be out injured, South Africa's selectors on Sunday (March 18) drafted in Duanne Olivier, the paceman, and Chris Morris, the fast bowling-allrounder, to make for an extended 17-man squad for the remaining two Tests against Australia. "I'm sure he'll expect them to say something on the field and he'll be prepared for that".
The 41-year-old Lee, a fearsome fast bowler during a sparkling career for Australia from 1999 to 2012, told AFP that controlled aggression is good for the sport.
"In any hearing you've got to be as happy as you can be".
