Schalk Burger could be a late withdrawal for the Stormers against the Brumbies has he struggles with a groin injury.
The loose forward is highly unlikely to feature according to Supersport after picking up the knock in training, with Michael Rhodes set to take his place in the team.
That would see Siya Kolisi shift across to the other flank, with Nizaam Carr continuing at number eight in the absence of Duane Vermeulen.
The Brumbies, on the other hand, should be at full strength, with David Pocock having been cleared to play after going through the concussion protocols.
Stephen Larkham announced a late change to his team yesterday with Matt Toomua fit to take his place in the centre and replacing Robbie Coleman in the starting lineup in Cape Town.
The Brumbies last won in Cape Town back in 2010, but came within a point earlier this season, only for Christian Lealiifano to miss a late shot at goal.
If the Australian side win they will travel to Wellington to face the Hurricanes in the semi-final, while a Stormers victory would see them take on the Waratahs.
