The Blues have reached the Super rugby semi-finals thanks to a 26-12 win over the New South Wales Waratahs on Friday in the first elimination qualifier at Auckland's Eden Park .
However All Black lock Anthony Boric limped off late in the game with a foot injury and coach Pat Lam is resigned to being without him next weekend.
The Waratahs scored the first and last tries, but after a strong start they let the Blues equalise through left- wing Lachie Munro, who also kicked two penalties to help the home side to a 13-8 half-time lead.
The Blues dominated the second spell in front of a disappointing crowd of 16,100 and finally outflanked the Waratahs defence when lock Ali Williams crossed for their second try with about 16 minutes to go, to make sure of the win.
If the Crusaders beat South Africa's Sharks in Nelson on Saturday night, the Blues will play the Queensland Reds in Brisbane.
If the Crusaders lose they'll go to Cape Town to play the Stormers.
