Smith earns 50th cap
Smith will run out in the starting side for his 50th Super Rugby cap against the side he made his Super Rugby debut for back in 2012. Alexander has been switched to the reserves list.
Smith will start in the front row alongside Scott Sio and Stephen Moore. Moore will break Nathan Sharpe's record for most Super Rugby caps for an Australian player when he runs out onto GIO Stadium.
Moore is currently equal with Nathan Sharpe on 162 career caps and will move into outright third on the all-time Super Rugby list with 163 when he takes to the field on Saturday.
Rory Arnold and Sam Carter will line up in the second row while Scott Fardy has been named at blindside flank after leaving the field with a head knock during the match against the Blues.
Jarrad Butler starts at openside flanker while rookie Michael Wells retains his position at No.8.
Tomás Cubelli will start at scrumhalf while co-captain Christian Lealiifano will start at flyhalf. Matt Toomua and Tevita Kuridrani are the centres while Nigel Ah Wong and James Dargaville remain on the wing. Aidan Toua has been named at fullback.
Aside from Smith and Alexander trading places, the reserves list is unchanged from last week. Josh Mann-Rea, Allan Alaalatoa, Alexander, Blake Enever and Tom Staniforth are the forwards on the bench while Joe Powell, Andrew Smith and Lausii Taliauli make up the reserves list.
Injured players Jordan Smiler and David Pocock both trained with the squad this week as they continue rehabilitation from injury. Joe Tomane was earlier this week ruled out for the remainder of the season due to a fractured tibia from a tackle during an appearance in club Rugby last weekend.
A bonus-point win for the Brumbies will ensure a spot in next week's Super Rugby finals.
The Brumbies have won eight and drawn one of their last 10 games against the Force including a current winning streak of five games. The Brumbies defeated the Force at nib Stadium 31-14 in Round Three of the 2016 Super Rugby season.
