Romano is the other front-line concern. In Brodie Retallick's absence he has pushed into the starting second-row alongside Crusaders team-mate Sam Whitelock but at present remains under a cloud with an inner ear cut and sore foot. If Romano does not recover, Scott Barrett may slot in. Patrick Tuipulotu also put his hand up with one of his best performances for the All Blacks in Lyon.
The Blues lock dropped the opening kickoff but scored a timely barge-over try and elsewhere produced an aggressive display which included one brutal hit that knocked out French No 8 Marco Tauleigne.
"I always want to be physical especially in my role as a lock," Tuipulotu said after the second-string All Blacks held on for a 28-23 win over the French XV on Wednesday (NZT).
"With a lot of young guys and new people it was probably more on me to lead the physicality. It felt good when I tackled him... hopefully he's alright now."
The All Blacks also need to gauge the fitness and fatigue levels of others who featured against the French XV. Backing up in a test match four days later is not commonplace.
Top of that assessment list is first-choice blindside Squire, a force down the left edge with ball in hand and on defence in 52 impressive minutes in his first game back from a virus in Lyon.
Vaea Fifita continued his progression at No 6 in Paris, and could do so again against Scotland if Squire is deemed too banged up.
Chiefs hooker Nathan Harris, needed to support Codie Taylor after Dane Coles' season-ending ACL injury, got through a power of work in his 62-minute stint, while back up playmaker Lima Sopoaga came off after 55 minutes; replaced by Richie Mo'unga who has since returned home with the five other All Blacks that turned out for the Barbarians.
The availability of all will, now, not be known until Friday (NZT).
