The DHL Stormers will have to take on the Southern Kings this weekend without a few of their backs which will make way for yet another shuffel in the back line.
Kolbe, Jean-Luc Du Plessis and Dan Kriel will not be playing this weekend after last week win over the Jaguares at Newlands.
Kolbe sustain a lateral ankle ligament injury with Kriel and Du Plessis being rested as precautionary measurement.
Both Kriel and Du Plessis sustain minor groin strains.
The Kings will host the Stormers in PE at 15:00 on Saturday and will be broadcast live on Super Sport.
