All Black hooker Dane Coles will miss their Rugby Championship opener against Australia after suffering a head knock in a warm-up match.
Coles, who only recently returned from injury, which included concussion symptoms, is set to return for the home game against Australia.
His Hurricanes team-mate Ricky Riccitelli has been called into the squad as cover, with Codie Taylor now expected to start their opener.
All Black coach Steve Hansen, who's also released Nehe Milner-Skudder and David Havili from his squad, played down Coles' problem.
"It's nothing too serious but enough for us to say that we don't want to play him. He should be available for Dunedin," he revealed to Stuff.
