The waiting game continues on the All Blacks casualties front.

Encouragingly, right wing Nehe Milner-Skudder's shoulder issue appears on the mend but loosehead prop Wyatt Crockett remains a doubt for the World Cup semifinal against the Springboks at Twickenham on Sunday (NZ time).

Milner-Skudder did not return after half time in the All Blacks crushing 62-13 win over France. He was replaced by Beauden Barrett with Ben Smith switching from fullback to the wing. But assistant coach Ian Foster painted a positive picture of Milner-Skudder's chance of recovering to keep the No 14 jersey this week.

"Nehe is progressing really well. There's certainly improvement there," Foster said. "Wyatt we are not so sure about. We'll have a good check through them tomorrow."

Probed on whether Crockett was likely to miss the semi, Foster remained coy.

"It's a possibility. There's been some progress but we'll see what happens in the next 24 hours. He's had a groin injury and it's just time now."

Crockett's probable absence would open the door for Joe Moody to start.

After coming on in the 28th minute against France, Moody was impressive last week, setting up one of Tawera Kerr-Barlow's two tries with a slick offload and packing down for seven scrums.

Despite already losing centurion Tony Woodcock to a tournament-ending hamstring injury the All Blacks will be more than confident in Moody's ability to handle the step up against the Boks and huge sense of occasion, should Crockett be ruled out.
