Perth-born inside centre Luke Burton will make his Super Rugby debut when the Western Force face the Stormers in Cape Town on Saturday.
The 20-year-old re-joined the Force squad for their South African tour after being a part of the Australian U20s side that defeated Samoa U20s, 34-5, late last month. Burton has been selected in the Australian squad for his second IRB Junior World Championship in June.
Burton replaces Kyle Godwin, who has been ruled out with a knee injury, and will form a new centre pairing with Chris Tuatara-Morrison, who has been promoted to the starting line-up.
Former Stormers outside back Marcel Brache shifts from outside centre to the wing in place of Dane Haylett-Petty, who will miss the match due to a groin injury.
Brache played four seasons with Western Province's Currie Cup side and made his Super Rugby debut for the Stormers against the Lions in 2012.
Brache will link up in the Western Force back three with both of last weekend's try scorers, Nick Cummins and Jayden Hayward, while Ian Prior and Sias Ebersohn will continue their combination in the halves.
The Western Force has named an unchanged forward pack for Saturday's match, while Patrick Dellit comes into the squad in the only change on the bench.
Force head coach Michael Foley believes it's important that his side finishes the two-match South Africa tour with a strong performance.
