Brache starts for Force
Outside centre Marcel Brache will earn his first opportunity in the starting line-up when the Western Force host the Waratahs.
The Force return home on the back of four successive victories looking for an improved performance against a Waratahs line-up that claimed the two sides' opening match of the season, 43-21, in Sydney.
Brache, who has come off the bench in two matches for the Force this season, retains the outside centre role after replacing the injured Solomoni Rasolea - who fractured his wrist - during the Force's 32-29 win over the Queensland Reds last weekend.
Brache's inclusion is the only change to the Western Force starting line-up, while Chris Tuatara-Morrison is in line to make his Super Rugby debut after being named on the Western Australian reserves list.
Western Force head coach Michael Foley says his side is looking forward to the challenge of taking on one of the competition's front-runners.
"We were extremely pleased with the result against the Reds - in particular seeing our whole bench close out the game after an enormous effort from the starting XV," said Foley.
"Having said that, we acknowledge there were some areas of our game that need to be better if we're to get the result this weekend."
