Rabada made contact with Smith's shoulder after dismissing him during the home side's six-wicket victory in Port Elizabeth.
"Haven't really seen the footage of this incident but by the looks of this".
Smith denied after the second Test that he tried to coax Rabada into a mis-step that would land him in strife again.
But the Proteas will surely base their appeal on both players making contact with each other, which raises questions over why just one party was charged and not the Australian captain. Trying some football skills to get a penalty???
A tweet from Vernon Philander's account - which the paceman on Thursday morning described as being "hacked" - rather sillily accused Smith of simulating the whole incident, expressing surprise that he did not dive to the ground as well. "Sorry for all the drama or entertainment caused", he wrote on Twitter, deleting the previous message.
"He told the world what he was going to do and what's more he's gone about and done it, and taken it to another level ..."
Cricket fans back Rabada after shirt-sleeve 'bust-up'
Rabada picked up a two-match ban for his behaviour in the first two tests against the Aussies, including getting too close to the batsmen in a competitive, fiery opening to the series. He was 25 percent of his match fee and received one demerit point. "I can't keep doing this because I'm letting the team down and I'm also letting myself down", he said.
However, Kagiso Rabada later appealed the guilty verdict handed to him by the International Cricket Council (ICC) for breaching their code of conduct in a last-ditch bid to be able to play in the rest of the gripping Test series.
Border, who is now in South Africa serving as a commentator for SuperSport, said that Rabada's ban would be an advantage to the visiting team. Warner claimed de Kock had said something personal about his wife, while South Africa claimed Warner had got personal first. Warner was caught on CCTV shouting at de Kock in the stairwell at Kingsmead, as the players went to their dressing room for tea on the fourth day of the match.
"I'm not suggesting for a minute we have silence out in the middle, but there's no doubt it's getting worse". The likelihood is that the hearing will happen before the third Test gets underway at Newlands on March 22, but the judicial commissioner could take some time to reach a decision.
"It's the accumulation of points, it's not an isolated event", he told Wide World of Sports.
