South Africa keeper Quinton de Kock's level-one charge for bringing cricket into disrepute has been upheld.
De Kock fronted a hearing chaired by match referee Jeff Crowe in Port Elizabeth today, having been booked for his role in an ugly staircase scrap with David Warner during the first test.
South Africa argued de Kock was provoked, but Crowe ruled the original punishment of one demerit point and a fine should stand.
Warner accepted his level-two charge, resulting in a fine of about AU$13,500 and three demerit points.
South Africa made the extraordinary decision to appeal de Kock's penalty for making disparaging remarks about Warner's wife despite his captain's admission of players directing personal abuse at Australia.
