Richie McCaw will start on the openside flank and Dan Carter at fly-half when the Crusaders face the Bulls in Pretoria on Saturday.
Those are just two of the five changes which head-coach Todd Blackadder has made to his starting line-up that beat the Cheetahs in Christchurch last weekend.
There are also two rotations in the front row, with prop Joe Moody and hooker Ben Funnell taking the starting spots this week in place of Wyatt Crockett and Codie Taylor who are both on the bench.
McCaw returns to play this week at seven, while Matt Todd will provide loose forward cover from the bench.
Carter will also play in his traditional number 10 jersey, which sees Tom Taylor move into inside centre and Colin Slade preparing to make an impact from the reserves.
Crusaders: 15 Israel Dagg, 14 Kieron Fonotia, 13 Ryan Crotty, 12 Tom Taylor, 11 Nemani Nadolo, 10 Dan Carter, 9 Andy Ellis, 8 Kieran Read (c), 7 Richie McCaw, 6 Jordan Taufua, 5 Sam Whitelock, 4 Luke Romano, 3 Owen Franks, 2 Ben Funnell, 1 Joe Moody.
