New Zealand coach Steve Hansen expects fly-half Dan Carter to be available for Saturday's Rugby Championship game against Argentina in La Plata.
Carter has missed the All Blacks' last two matches - home victories over Argentina and South Africa - with a calf injury but is likely to replace Aaron Cruden if he is passed fit.
"He's training like he's ready to play, so as long as he continues to progress he'll be playing," said Hansen on Tuesday.
"He came through today's session pretty good. We pulled him out after about 45 minutes and he wasn't overly happy about that, he wanted to do a bit more so that was a good sign."
The All Blacks will clinch the title if they beat the Pumas regardless of what happens in South Africa's clash with Australia in Pretoria.
However, Hansen is expecting a tough test after Argentina's near miss against Australia when they threw away a 13-point lead in a 23-19 defeat.
"They started to use the ball a bit against Australia and looked really dangerous so they might get some confidence out of that and maybe play some more rugby," he said.
