Bulls boss Frans Ludeke has made three changes, all in the pack, for Saturday's Super Rugby clash with the Lions at Ellis Park.
Jacques Engelbrecht moves from the bench to start at number eight, with Grant Hattingh moving to lock in place of Victor Matfield who is rested. In another rotational swap, Marcel van der Merwe will start at tighthead, with Werner Kruger playing off the bench.
Wimpie van der Walt replaces Engelbrecht on the bench, where there is also a return for Louis Fouchè. The fly-half will replace Handrè Pollard, who is captaining the Junior Springboks in New Zealand. William Small-Smith is also back after illness and replaces Ulrich Beyers on the bench.
Ludeke confirmed his team's desire to make the play-offs.
"We have to win every remaining match, so are keen to keep on the winning track," said Ludeke.
"It will also be important for us to go into the break with some momentum. We have made some minor changes and I believe we will be competitive against a team that will be very dangerous at home. We cannot afford to let them dominate the pace of the match or the style of play."
