Ireland will be boosted by the absence of All Blacks second row Sam Whitelock in this Saturday's second Test, according to Bernard Jackman.

The 133-cap Whitelock will miss this Saturday's Test in Dunedin, having reported concussion symptoms following New Zealand's 42-19 win against Ireland in Auckland.

The 33-year-old's place in the team has been filled by flanker Dalton Papalii, while Scott Barrett reverts to his usual spot in the second row.

Crucially, the veteran lock is Ian Foster's regular lineout caller, a role that will now be filled by Brodie Retallick. And with Papalii more known for his work as a ball-carrier, it removes a major threat from the All Blacks lineout, which caused Ireland a lot of disruption last week.

"He's a big loss," said Bernard Jackman on this week's RTÉ Rugby podcast.

"He had a pretty poor game in Dublin in November, he got rattled and I thought he was outstanding last week. Someone of his experience, there are certain games they know they want to nail, and he nailed it.

"Obviously the fact Scott Barrett moved from six into the second row removes one of their defensive lineout options, again that should help us.

"Papalii is a bigger ball-carrier but he's less of a lineout option, and they brought Patrick Tuipulotu onto the bench who is a very powerful player."

And although the three-time world champions have lost their most experienced active player, and a forward who has previously captained the team, Jackman says it's still an All Blacks team loaded with quality.

"Will Jordan coming back onto the bench is a boost for them, because a lot of people think he would have started the first Test only for Covid.

"I do think Whitelock [being absent] is a boost for Ireland, but it's certainly a very talented and exciting All Blacks 23, even with his omission."

Ireland head coach Andy Farrell has also just made one change, with Mack Hansen replacing Keith Earls, having missed the first Test due to Covid isolation.

And Jackman believes Farrell is right to give the majority of last week's team a chance to right the wrongs of Auckland.

He said: "Keith Earls is quality, Hansen potentially will offer something a little different, but that wasn't the winning and losing of the game [last week].

"You'd hope with the roof being closed that will help the handling. We gave away too many unforced errors in terms of our ability to move the ball across the backline, which is something Ireland have been good at.

"I think the fact he's able to go with a very settled team again, it's effectively our best team, we'll hopefully see an improved performance.

"I'm fascinated to see in Test two how we improve. I hope we improve, and obviously put in a more competitive performance."
