Earlier, Rabada was suspended for South Africa's remaining two Tests of the four-match series against Australia after being found guilty of a Level 2 ICC Code of Conduct offence of "inappropriate and deliberate physical contact with a player".
Rabada's public admission, though, which came after a discussion with his father, suggested he was all but resigned to sitting out the final two matches of the series.
New Zealander Michael Heron has been appointed as the judicial commissioner for the hearing, which will be held via video conference on Monday, the ICC said in a statement. Harris tweeted about Kohli while talking about Rabada's suspension by the ICC, which will see him miss two Test matches against Australia.
"I think I take responsibility for what happened", Rabada told press at an appearance at a junior coaching clinic in Centurion.
"I do things because I'm passionate".
"Our strike rate is zero per cent at the moment with trying to challenge these cases, it will probably stay at zero", du Plessis said after the second Test.
There is a groundswell of support here for Rabada, who will be represented by one of the South Africa's most high-profile legal figures, Advocate Dali Mpofu, in the hearing.
Smith was consulting with his batting partner about the merits of a review when the paceman brushed him while unleashing a screaming send-off.
Since Heron's ultimate decision will be delivered on Wednesday, there is still a chance that Rabada will feature in the third Test in Cape Town.
