Beale has been named in the starting lineup, but if his hamstring problem worsens, then Adam Ashley-Cooper will switch from outside centre to replace him and Anthony Faingaa will take Ashley-Cooper's place in the midfield.
Should Faingaa be needed on the pitch, Rob Horne will step up to the bench.
"We will leave it as long as we can before making a decision," said coach Robbie Deans. "It will be tough on Kurtley if he has to miss this one, but we will take no chances.
"If he can't play, he will contribute off the field as he always does. Adam and Ant are both good men. They will do a more than capable job in Kurtley's absence."
