Wilhelm Steenkamp has replaced Flip van der Merwe in the only change to the Bulls starting side for their derby against the Lions at Loftus on Saturday.
Van der Merwe was ruled out earlier this week, but Steenkamp is an experienced and competent replacement. Flank Deon Stegmann comes onto the bench after recovering from a broken arm suffered earlier in the season.
Bulls coach Frans Ludeke said flank Jacques Potgieter will provide cover at lock.

Subs: 16 Willie Wepener, 17 Frik Kirsten, 18 Deon Stegmann, 19 CJ Stander, 20 Jano Vermaak, 21 Louis Fouché, 22 Francois Venter.
