South Africa head coach Heyneke Meyer has blasted his team's ill-discipline during their 21-11 loss to New Zealand.
Springboks prop Dean Greyling was given a yellow card for a forearm to Richie McCaw's face for which he is expected to be cited.
"I'm very big on discipline and it's unacceptable," said Meyer.
"I think it cost us the game as well and I want to apologise to Richie and it will be dealt with inhouse, but it's unacceptable. We're a team that prides ourselves on discipline and we can't afford these things in games."
The indiscretion is South Africa's second in as many matches.
