Openside flanker Jack Lam, who has a minor hamstring strain, has been bracketed with Karl Lowe. Chris Eaton is at halfback and Brad Shields at No8.
An obvious replacement for Dagg would have been Tasman fullback Tom Marshall, but a serious shoulder injury suffered in club rugby has ruled him out, and Sean Maitland could be drafted into the last line of defence. Tom Taylor or Tyler Bleyendaal are options at first-five, with either Richie McCaw or Luke Whitelock to wear Read's No8 jersey.
Dagg, who scored a try after spraining his ankle in the second half at Waikato Stadium, stayed on the field, but the joint remains painful. He will be a big loss to the Crusaders, who are second in the New Zealand conference and looking for maximum points to keep the pressure on the table-topping Chiefs.
While the Hurricanes have been boosted by the return of their new All Blacks, including wing Julian Savea, who scored a hat-trick on debut in the first test against Ireland, and first-five Beauden Barrett, outstanding as a replacement in Hamilton last weekend, the Crusaders welcome back lock Luke Romano, who also played well at Waikato Stadium.
Super Rugby action returns after a three-week break with tomorrow night's match between the Highlanders and Chiefs in Dunedin. The Highlanders will be at full-strength, with flanker James Haskell, who played for England in their 14-14 draw against the Springboks in Port Elizabeth in the weekend, available for the southerners.
Haskell tweeted on his arrival back in New Zealand on Tuesday: "Finally back in NZ this morning, after the longest flights and layovers ever. Not feeling fresh. Amazing experience with England, though.''
Aaron Cruden, who aggravated an Achilles tendon injury in his short but scintillating appearance for the All Blacks in the weekend, will play for the Chiefs, who are boosted further by a flood of fellow in-form All Blacks in Sonny Bill Williams, Brodie Retallick, Sam Cane and Liam Messam. Perhaps surprisingly, coach Dave Rennie has decided to leave openside flanker Cane on the reserves bench in favour of Tanerau Latimer.
The Highlanders will name their team today.
The Blues, last on the table, have a bye this weekend.
