Giteau has struggled with a quadriceps injury for the past fortnight and has managed only limited training sessions with his teammates.

Coach Andy Friend will put Giteau through a strenuous training run in Perth tomorrow before deciding whether or not the 27-year-old will play.

Matt Toomua is on standby to replace Giteau should he fail his final fitness test.

In other team news veteran Justin Harrison has beaten Ben Hand to a starting lock role, Ben Alexander and Rocky Elsom have both recovered from injury and will start while Pat McCabe has been named on a wing to make his Super 14 debut.
