South Africa will resume tonight on one for 39.
Rabada finished with five for 96, having done all his damage on either side of tea, taking the key wicket of Australian captain Steve Smith, then following up by dismissing the Marsh brothers, Shaun and Mitchell, in his next over.
Australian players and officials are reportedly outraged about the photo.
Overcast conditions on a pitch with a healthy grass cover meant the tourists scored just 23 runs in the first 14 overs as the home bowlers found prodigious movement but then Warner seemed to switch gear and, together with Cameron Bancroft, plundered 75 runs in the remaining 12.4 overs of the session. Match referee Jeff Crowe also called the captains and managers to a meeting on the eve of the second test in an attempt to calm the situation.
Cricket Australia's (CA) digital arm has stepped in to provide coverage in New Zealand of the remainder of the ongoing Test series between Australia and South Africa.
There were few alarms from the wicket, which did not provide the same seam movement that South Africa enjoyed on the first day when they restricted Australia to 243 all out.
"I haven't read it", Lyon said, adding he wasn't aware there was a message. That would take Rabada to eight, which would mean he misses the rest of the Australia series. Paine was last man out for 36. First Bancroft was caught behind for 38 to signal the break, before Usman Khawaja fell in similar fashion.
Both Warner and de Kock received fines and disciplinary sanctions after their altercation in Durban.
That wicket inspired Rabada, though, and Shaun Marsh (24) went lbw after another poor review before his brother Mitchell (4) followed three balls later with an inside edge to De Kock to signal tea. Fast bowler Kagiso Rabada faces a hearing on Saturday that could result in a ban from the third Test against Australia.
Following that heated showdown last time out, Du Plessis also expects that Australia will continue to sledge in Port Elizabeth.
Paine was equally confident that the drama leading up to the second Test here at St George's Park will not affect Warner's performances at all.
