Blues midfielder Francis Saili is out of Friday's match against the Reds at Eden Park after limping out of training.
Saili collided with another player during a defensive session and initial impressions were of an ankle fracture, however x-rays were clear and it appears he has suffered an ankle sprain.
Jackson Willison comes into the team to replace him.
