Bulls head coach Frans Ludeke has made three changes to his starting XV for Saturday's clash with the Lions at Ellis Park in Johannesburg.
Ludeke makes two alterations to his pack and also replaces injured pivot Handré Pollard, who did not recover in time from a knee contusion.
Jacques-Louis Potgieter will start at fly-half and is the only change to the back-line that ran on against the Crusaders last weekend. Potgieter is returning to action following a hamstring strain that kept him out for three weeks.
Grant Hattingh (for Victor Matfield) and Dean Greyling (for Morné Mellett) will start in the pack.
Both played off the bench last weekend.
Hattingh's spot on the bench will be taken by Roelof Smit and Greyling swaps places with Mellett, who will play off the bench. Matfield is rested as is centre Jan Serfontein while hooker Callie Visagie makes a return to the squad following a back injury.
Ludeke is keen for the team to continue with the rugby that earned them four wins on the trot, but realises the challenge that will come from the home side.
Bulls scrum-half Piet van Zyl will earn a 50th Super Rugby cap if he takes to the field. The 25-year-old played his first 32 matches in the competition for the Cheetahs.
Bulls: 15 Jesse Kriel, 14 Francois Hougaard, 13 JJ Engelbrecht, 12 Burger Odendaal, 11 Bjorn Basson, 10 Jacques-Louis Potgieter, 9 Rudy Paige, 8 Pierre Spies (c), 7 Hanro Liebenberg, 6 Deon Stegmann, 5 Grant Hattingh, 4 Jacques du Plessis, 3 Trevor Nyakane, 2 Adriaan Strauss,1 Dean Greyling.
