David Warner and Quinton de Kock have been charged with bringing cricket into disrepute over the staircase stoush that has overshadowed the Test series between Australia and South Africa.
Warner has been issued with a level-two charge by the International Cricket Council for conduct that brings the game into disrepute, while de Kock has been slapped with a level-one infraction.
Under the ICC's code of conduct regulations, Warner's charge is the more serious.
The two sides are yet to announce whether they will appeal match referee Jeff Crowe's assessment of the off-field scrap between Warner and de Kock that occurred at tea on day four of the first Test.
Both teams have until Wednesday to respond but, while de Kock can only receive a maximum of two demerit points, Warner's level-two charge means he stands to be hit with three or four points.
If it was four he would be banned from the second Test starting on Friday.
ICC match referee Jeff Crowe met with Australian and South African team management including Australian coach Darren Lehmann late on Tuesday at the hotel where both sides are staying.
