Robbie Coleman has been ruled out of the Brumbies clash against the Rebels, to be replaced by James Dargaville.
Coleman complained of stiffness in his hamstring following an 80-minute performance against the Bulls, where he had replaced injured Matt Toomua.
Dargaville will shift from the wing to inside centre for Friday night's match, with Lausii Talauli starting on the wing and Brumbies Colts captain Jordan Jackson-Hope coming into the match-day 23.
It will be Dargaville's first game at 12 for the Brumbies, though he played his whole junior career in that spot and had four games there in the NRC for finalists, UC Vikings.
