All Blacks prop Fletcher Newell has been ruled out of the upcoming Rugby Championship test against Australia due to a calf injury sustained during New Zealand's recent 18-12 loss to South Africa. Newell, who was a substitute during that match, is expected to be sidelined for three to four weeks, which raises doubts about his availability for the second test against Australia in Wellington later this month. In his absence, Ethan de Groot, who has recovered from a neck injury, and George Bower have been called up to the squad. Both teams are looking to turn around disappointing performances, with New Zealand having lost three of their last four matches and Australia sitting at the bottom of the Rugby Championship table. The All Blacks hope to exploit Australia's weaknesses, especially after the Wallabies' heavy defeat to Argentina. New Zealand will not defend their Rugby Championship title after their recent losses, intensifying the stakes for the upcoming match.
