Key backs Israel Dagg, Seta Tamanivalu and Richie Mo'unga remain sidelined with injuries, while All Blacks skipper Kieran Read is only two weeks shy of an expected first start of 2017.
Read is scheduled to play club rugby next week.
The Crusaders have won all five games, but needed to mount furious comebacks in three of them, before last week's romp against the Force in Christchurch.
The Waratahs launched their own comeback last week to down the Rebels 32-25, ending a string of three losses.
The New South Wales side will be buoyed by having beaten the Crusaders in their past two meetings in Sydney, including the 2014 final.
