The Sharks rake is out for the Investec Rugby Championship and has been replaced by Craig Burden, also from the Sharks.
Meyer said after his side's 27-6 win that the Argentinians had the better of South Africa at the breakdown.
"We didn't handle that on the day and there is no use saying afterwards that we need to be more clinical. We need to make a huge step up at the breakdown," he said.
"I thought our kicking game was a lot better than against England. I think the problem was that when we got into the areas, we kept the ball through two or three phases then lost the ball at the breakdown."
Argentina had impressed with their defensive effort to deny South Africa the chance to launch a killer blow in the game.
Argentina had been right on the advantage line and in the Springboks faces.
"They pressed hard in the midfield which we knew they would do and we didn't get quick ball," he said.
However, the effort had been an improvement on the final Test against England and there were no soft moments in defence.
"I'm probably a very difficult coach to please. I would have loved to get four tries, but this is Test match rugby," he said.
"I was very happy on defence, we've worked really hard on it, and they didn't score any tries."
First five-eighths Morne Steyn had been under pressure going into the game but had responded to the selectors' faith in him.
"Morne trained well the whole week and I felt he would have a great game. I'm just happy he delivered. It's just the kind of guys he is – we needed him today and I thought he was awesome," Meyer said.
Steyn landed all five goal attempts he had.
As he looked to the return match in Mendoza at the weekend, Meyer said the side would also need to brush up on its decision-making.
"I thought we should have finished a bit better once or twice and gone for the four tries. But this team is still improving and the guys put their bodies on the line and I can't ask for more," he said.
