If Burger doesn't recover from his injury in time, it's likely that Luke Watson will take over the number six jersey and have the responsibility of fighting for the ball on the ground.
There was talk at the start of the season that Watson would be shielded from local derbies because of his anti-Springbok and derogatory Afrikaans comments last October, as was the case against the Sharks when he was brought on as a subsititute. But that way of thinking seems to have changed with! Watson likely to start.
Duane Vermeulen will shift! back to his more favoured number eight position with Francois Louw coming back into the starting fifteen. There's also talk of Willem de Waal replacing Peter Grant at flyhalf, suggesting the Stormers will be using the boot a lot against the men from Pretoria.
