Brumbies unchanged for Rebels
The experienced front row of Scott Sio, co-captain Stephen Moore and Ben Alexander pack down in the front row while Rory Arnold and Sam Carter are the starting locks.
Scott Fardy, David Pocock and Jarrad Butler make up the backrow while Tomás Cubelli and co-captain Christian Lealiifano form the halfback combination.
Robbie Coleman and Tevita Kuridrani pair up in midfield, while James Dargaville and Nigel Ah Wong will start on either wing and Aidan Toua is the fullback.
Larkham was impressed with the work of his reserves last week and will go with six forwards and two backs again.
Josh Man-Rea, Allan Alaalatoa and Ruan Smith all performed well off the bench last week and return alongside Tom Staniforth, Blake Enever, Jordan Smiler, Joe Powell and Lausii Taliauli.
