Cape Town - Scrumhalf Ryan Louwrens will make his Super Rugby run-on debut when the Western Force take on the Blues at Eden Park.
The 24-year-old South African-born scrumhalf made an impressive tournament debut against the Chiefs in Hamilton last weekend, and will wear the No 9 jersey in place of the injured Alby Mathewson (knee) and Ian Prior, who is serving a three-week suspension.
Louwrens' promotion is the only change to the starting XV, while lock Adam Coleman has been bracketed with Wilhelm Steenkamp after sustaining a knock to his shoulder against the Chiefs.
