By selecting Ben Tameifuna at prop, Chiefs coach Dave Rennie is hoping to spike the Crusaders' scrum with the biggest piece of artillery he has.
The 140kg Tameifuna made his considerable presence felt when replacing recent All Blacks debutant Ben Afeaki at tighthead in the second half of the Chiefs' victory over the Hurricanes last weekend.
Tameifuna's impact was also obvious around the field when he scored one of the Chiefs' four tries charging through a breakdown.
Now the 21-year-old gets another chance against one of the best scrums in the competition.
The Crusaders boast eight current or former All Blacks in their pack, and 12 in their starting line-up.
"The key thing is they've got a really good scrum and their set piece is a real weapon for them both with and without the ball," Rennie said.
The Chiefs coach dodged the question of whether Tameifuna's selection was an attempt to put pressure on Wyatt Crockett, the Crusaders loosehead.
There is no doubt that Crockett, now probably the best loosehead in the country, will find it more difficult to manoeuvre Tameifuna than he would Afeaki.
Meanwhile, Rennie said he would not be interested in signing contentious Highlander Ma'a Nonu for the Chiefs if Sonny Bill Williams doesn't return next year.
