Schalk Burger is struggling with a calf injury and could miss the make-or-break bout with the Bulls at Loftus Versfeld.
Burger hurt his calf in the loss to the Blues and at this stage looks unlikely to take the field in Pretoria. Francois Louw should slot in at openside with Duane Vermeulen retained at 7 and Luke Watson at 8.
Although they did not train on Monday or Tuesday, props JD Moller and Brian Mujati should be fit for what it a crucial forward scrap. Given the physical nature of the contest, AJ Venter could also start in the second row ahead of Adriaan Fondse.
The Stormers have lost two of their first three matches. If they lose to the Bulls and beat the Lions, they will head Down Under with a two from five record. However, given the length of the tour and quality of the opposition, the Stormers may struggle to pick up sufficient points to challenge for a top-four spot. This is why the Bulls match is so crucial to their chances.
