The Blues will wait until Friday before deciding whether Isa Nacewa is fit to return at fullback for the Super 14 rugby match against the Brumbies in Auckland on Saturday.
Nacewa has been sidelined with a knee injury since the Blues' round three defeat of the Cheetahs inBloemfontain early last month.
He has been bracketed with Ben Atiga for the No 15 jersey against the Brumbies at Eden Park.
Coach David Nucifora said Nacewa would be assessed again tomorrow and a decision made the following day.
In one of three changes to the 15 that started in the loss to the Waratahs last weekend, Nacewa or Atiga will replace George Pisi, who has a hamstring strain.
Rudi Wulf will come on to the left wing for Joe Rokocoko, whose Super 14 season has been ended by a wrist problem.
In the forwards, lock Anthony Boric will start in place of Kurtis Haiu, who has been rested and drops out of the 22.
Blues Isa Nacewa/Ben Atiga, Anthony Tuitavake, Isaia Toeava, Benson Stanley, Rudi Wulf, Nick Evans, Danny Lee, Nick Williams, Daniel Braid, Jerome Kaino, Troy Flavell (captain), Anthony Boric, John Afoa, Keven Mealamu, Tony Woodcock.
