SONNY Bill Williams’ All Blacks return lasted only a few hours as the star centre was initially named on the bench to play the Springboks then scratched later on Thursday morning due to illness.

There are 10 changes to the run on side and five on the bench in a strong All Blacks combination looking to extend their unbeaten record in the fourth round Rugby Championship match in Wellington.

Ryan Crotty, Sam Cane and Rieko Ioane all made the starting lineup after missing last week’s Test against Argentina because of injury.

“We know that we’ll have to be at our very best,” coach Steve Hansen said, noting that South Africa “will be desperate” following back to back losses to Argentina and Australia.

He opted for Crotty to start in the 12 jersey, having been given the all clear after being knocked out against Australia early in the series.

Williams, who has had little rugby in recent months and was unable to train fully during the week, was replaced on the bench by Jack Goodhue.

Veteran midfielder Williams missed the first two Tests against France in June following knee surgery, and played just 58 minutes of the third Test before injuring his shoulder and has been out of action ever since.

Since Williams’ All Blacks debut in 2010 he has missed 30 of New Zealand’s 77 Tests.

Aaron Smith and Beauden Barrett are reunited in the halves while Anton Lienert-Brown will play at outside centre.

Ioane returns from injury to the left wing, while Ben Smith moves to the right wing to make way for Jordie Barrett at fullback.

In the forwards, Sam Whitelock moves into the number four jersey, with Brodie Retallick injured, and Patrick Tuipulotu comes onto the bench as lock cover for his first Test of 2018.

Liam Squire and Cane return as flankers with Highlanders rake Liam Coltman promoted to back up hooker ahead of Nathan Harris.

“We’ve had a good week’s preparation, focusing on what we need to bring to the game through our skill sets, the intensity of our play and our energy,” Hansen said.

“We’ll have to be at our very best in all these areas to counter an opposition we know will be desperate following their back to back losses.

“That means we’ll have to respond with a quality performance and a real hunger to be better.

“You just have to look at our last encounter in Cape Town to understand what kind of beast we will be facing.”

The unbeaten All Blacks lead the Rugby Championship with 15 points from three bonus point wins.

South Africa, Argentina and Australia have one win each, with South Africa second on the table courtesy of two bonus points.

When the All Blacks last played South Africa, in Cape Town last year, they scraped home 25-24 to complete a clean sweep of the championship, after comfortably winning the first leg 57-0 in New Zealand.

The Springboks have made three changes to their starting lineup.
