It's all change for the Chiefs and an adjustment for the Blues as the franchise neighbours sift their front row resources for tomorrow's Super 15 duel in Hamilton.
Senior prop Charlie Faumuina has damaged a knee ligament although Blues staff hope he will be fit to leave at the weekend for the squad's two games in South Africa while the Chiefs have lost props Ben Afeaki and Toby Smith to long-term damage.
The rearrangements leave occasional Blues loosehead Tom McCartney to line up against massive rookie Ben Tameifuna whose 134kg frame gives him a 24kg weight advantage in his debut match for the Chiefs.
Tameifuna was part of the NZ under-20 side which won the world championship last year and was picked from Hawkes Bay as a front-rower with the potential to develop into a strong contender in his debut Super 15 season. But injuries mean he is needed now and will wear the No 3 jersey tomorrow with his cousin Arizona Taumalolo promoted to loosehead prop and Samoan captain Mahonri Schwalger starting this week as hooker.
Faumuina's place has been taken by Tevita Mailau in the one alteration from the Blues combination which started the opening loss to the Crusaders.
