Supporters leaned over the railings and verbally insulted Jones as he walked down the tunnel after the final whistle.
He stood his ground for 10-15 seconds before being led away by players and staff. Fullback Willie le Roux, another overseas-based player recalled by Erasmus, got the fourth for South Africa, which went to halftime 29-27 ahead. Especially when they win'.
However, Jones dismissed the incident as just "a little conversation about a bottle of wine" in his post-match press conference.
"It certainly wasn't the start we wanted in our first Test at home and I was anxious, because we had a lot of young players against a very experienced England side", said Erasmus.
England finished the stronger of the sides as Itoje stretched over the ruck to reduce South Africa's lead to 39-32 and then May ran though the home defence to leave the Boks three points ahead with one minute left.
"I thought we were just going to receive kicks and we would never have to defend", he said.
"I wouldn't worry about that because it was such a great game of rugby".
However, the hosts produced a sensational comeback, running in four tries - two of them from debutant winger Sibusiso Nkosi - to turn the game around before the break.
Aphiwe Dyantyi touched down in the second half and while England threatened late on, scoring two late tries, South Africa held on for a thrilling 42-39 triumph in a pulsating series opener.
"It was a wonderful game of rugby, but it's not good to sit in the loser's seat".
"There's no problem with our spirit and effort, what's wrong is a few slight individual errors and indiscipline".
"We had mambas, we had cobras, we had long green ones, long black-and-white ones... a snake's a snake to me!"
"We'll have a look at the game but we need to make sure that we stick together ... and that we get the technical bits right". "There was a lot of young guys on the park ... it could have gone really bad for us".
Billy Vunipola, fit again and playing his first global for more than a year, said: 'We'll work on our discipline this week, there's a lot we can work on, but I think we'll be fine.
Erasmus is back in the town where he hit the big-time while playing for the Cheetahs and where he started his coaching career.
However, England's 2003 World Cup-winning coach Clive Woodward told BBC Radio 5 Live: "Something is not right because they are normally very good defensively".
"Character is something we can take forward and build on‚" said the coach.
