Rugby: All Blacks star Rieko Ioane in doubt for second Bledisloe Cup test against Wallabies, Peter Umaga-Jensen called in as cover

Rieko Ioane may not get an immediate chance to make amends for his blunder in the first Bledisloe Cup test, as his status is in doubt for the All Blacks' clash against Australia at Eden Park tomorrow.

Ioane, who was dropped to the bench after losing the ball when diving to score a try in the 16-all draw with the Wallabies in Wellington last weekend, is in doubt with a hamstring injury.

Peter Umaga-Jensen has been called in as cover in case Ioane is not fit to play. A decision will be made tomorrow.

Umaga-Jensen had trained with the All Blacks earlier in the week but was released to play for Wellington against North Harbour this afternoon. However, Ioane's injury meant he was removed from the squad late in the piece to fly up to Auckland and link back up with the All Blacks.

Anton Lienert-Brown and Jack Goodhue will start in the centres, while Umaga-Jensen could join reserve prop Alex Hodgman in making his first appearance in the black jersey if he is required to sit on the bench.

The news would be another blow for the All Blacks backline after George Bridge was ruled out earlier in the week after a training injury.

Bridge is out for up to six months after suffering a chest injury in training, while Sam Whitelock is also out of tomorrow's match because of headaches.

Having made their debuts off the bench in Wellington, Caleb Clarke and Tupou Vaa'i moved into the starting lineup for the second test as their replacements.

Meanwhile, the Wallabies are sweating on one of their standouts from the draw in Wellington.

Harry Wilson had a strong debut at No 6 in the drawn match, and was moved to No 8 for tomorrow afternoon's clash. However, he was a notable absentee at today's captain's run due to illness, remaining at the team hotel with what was reported to be a stomach bug.

A Wallabies spokesperson told Australian media that Wilson struggled to sleep and team management thought it would be best to allow him to rest and rehydrate.

Wallabies captain Michael Hooper was hoping Wilson would be fit for a repeat performance of his impressive debut.

"He had a really good physical presence and some nice finesse in his carries down the edge there," Hooper said. "He was physical through the middle and his defence [was good]. More of the same from him."

Pete Samu, who was dropped from the 23, would be a likely replacement if Wilson was unable to play.
