Blackadder has made two changes in the forwards and one in the backs to play the Bulls at AMI Stadium in Christchurch.
Wyatt Crockett gets the start at loosehead prop with Ben Franks moving to the bench, while locks Sam Whitelock and Tom Donnelly switch positions from last week's 38-24 win over the Western Force.
Whitelock comes into the starting side and Donnelly moves to the bench.
Adam Whitelock moves back to the wing this week, vacating the outside centre position for Robbie Fruean, while Sean Maitland will provide cover from the bench.
The winner from this game will progress to the semi-finals, playing either the Chiefs or the Stormers depending on the result from the other qualifier match.
CRUSADERS: Israel Dagg, Adam Whitelock, Robbie Fruean, Ryan Crotty, Zac Guildford, Dan Carter (vc), Andy Ellis, Richie McCaw (c), Matt Todd, George Whitelock, Samuel Whitelock, Luke Romano, Owen Franks, Corey Flynn, Wyatt Crockett.
