The Brumbies have named their team to play the Bulls at Loftus Versfeld in Pretoria with Leon Power making his first appearance since the fifth round.
Power has been sidelined since the Waratahs game in round five after straining his knee and at 2 metres tall the lock adds height to the Brumbies line-out and a hard edge around the park.
With Power included at lock, Scott Fardy moves to the side of the scrum at blind-side flanker, Fotu Auelua and Jordan Smiler come onto the bench and Tom McVerry drops out of the match day 23.
Director of Rugby Laurie Fisher said his side had prepared well ahead of the match against the Bulls.
"We've had a good week of training in Johannesburg and the boys are excited by the opportunity to get back in the winners' circle on Friday night," Fisher said.
"The Bulls at Loftus is one of world rugby's great challenges. The Bulls lift to another level when they play on the high-veldt so we will need to be at our best.
"Our full focus is on making the most of the opportunities we will be presented, to stick to the processes we've worked on through the week and to come away from Loftus with a win."
The last time the Brumbies visited Loftus to face the Bulls was in 2013 during the Super Rugby Semi-Final.
A last ditched Toomua-to-Kuridrani ball handed the Brumbies a huge win, their second over the Bulls in 2013 after the Pretorians went down after the bell in Canberra two months earlier.
A year older, the Brumbies find themselves in another desperate situation, with the rest of the Australian Conference now breathing down their necks while holding an extra game to play.
