It’s a blow for the side to lose two members of their starting squad a week removed from a 21-point loss, while Mitchell Dunshea – who started in place of an absent Sam Whitelock last weekend – was also ruled out of the Highlanders clash due to a concussion.
The Crusaders, however, welcome Whitelock back into the fold. Christian Lio-Willie joins the starting side at No 8 in Grace’s absence, while Tamaiti Williams joins Joe Moody and Codie Taylor in the front row in Newell’s place.
Robertson has also rotated his backline, with Fergus Burke given the start at fullback as David Havili moves to second-five, pushing Braydon Ennor to the bench.
This week will be the first time since 2016 that the Crusaders come into the second week of a competition looking for the first win of their campaign; coincidentally that, too, was a week-one loss to the Chiefs in Christchurch.
Reflecting on last weekend’s defeat, Robertson said his side weren’t far away in a lot of areas, but they had clarity on exactly where they needed to focus their attention against the Highlanders.
“It was good until about 50 minutes,” Robertson said of the performance against the Chiefs. “But the context of the game, how many tackles we had to make, how we could’ve been better around a lot of areas like just getting out of our own part of the field. It was hard to get off our back fence and they did a great job. We learned a lot in round one. They’re a hell of a team. That was a pretty special performance from them and we could’ve been better. That was the margin.
“It’s important to focus on the things you just have to get right. There were some awesome efforts and some incredible individual efforts, there’s a couple of things in the game we just need to get those right and the rest works itself out. That’s been our focus from round one, just to clear our mind nice and early.”
The Highlanders, meanwhile, have rested all their All Blacks from their starting XV, with blindside flanker Shannon Frizell, loosehead prop Ethan de Groot and halfback Aaron Smith all not playing, while Folau Fakatava is on the bench.
Loose forward Marino Mikaele-Tu’u is also out injured, as is wing Jona Nareki.
