Pretoria - Bulls coach Frans Ludeke made one change to his starting line-up for Saturday's Super Rugby clash against the Stormers at Newlands in Cape Town.
Kick-off is at 18:10.
Bakkies Botha is unavailable after suffering a knee injury and his place at lock will be taken by Danie Rossouw, who moves from the side of the scrum.
Dewald Potgieter, who started off the bench against the Waratahs last week, slots back into the number seven jersey, which he has worn 11 times this season, and Derick Kuun moves to the bench in his place.
Losing Botha was a blow, Ludeke admitted, but added he was still confident about the trip south.
"Bakkies was due to play in his 100th game, so there is a lot of experience lost, but Danie will play in his 115th match," said Ludeke.
"Dewald started with this loose trio in 10 of our matches this year, so slots into an established unit. We have good momentum and we will back ourselves in this one."
Bulls captain Victor Matfield admitted to the importance of the clash.
"We can still finish top of the conference, but can also miss the playoffs altogether if we lose, so we still have all to play for," said Matfield.
"The focus on Saturday will be to execute the game plan in an accurate way and to use the opportunities that come our way."
