Lock Blake Enever and flank Lachlan McCaffrey will start for the Brumbies against the Bulls at Loftus on Saturday.
Enever replaces the suspended Rory Arnold, while McCaffrey comes in for the injured Rob Valetini.
Enever will partner co-captain Sam Carter in the second row for the first time this season, with the only previous time the pair have been selected in the same starting XV coming when Enever started in the back row in the round 11 match with the Crusaders in Canberra.
McCaffrey, meanwhile, slots back into the blindside role, having been named as a replacement in the defeat to the Lions at Ellis Park last weekend. The physical ball-carrier will be joined in the back row by David Pocock and Isi Naisarani.
The rest of the starting team is the same that played in Johannesburg, with the front row of Scott Sio, Folau Fainga’a and Allan Alaalatoa packing down together for the eighth match in succession.
Brumbies – 15 Tom Banks, 14 Henry Speight, 13 Tevita Kuridrani, 12 Kyle Godwin, 11 Andrew Muirhead, 10 Christian Lealiifano (co-c), 9 Joe Powell, 8 Isi Naisarani, 7 David Pocock, 6 Lachlan McCaffrey, 5 Sam Carter (co-c), 4 Blake Enever, 3 Allan Alaalatoa, 2 Folau Fainga’a, 1 Scott Sio.
