The Bulls will be without Springbok centre Jesse Kriel for the next six to eight weeks after he limped out of the Pretoria-based side’s 24-23 defeat to the Stormers at Newlands on Saturday.
Kriel has had successful ankle surgery.
Bulls team doctor Herman Roussow confirmed that Kriel had torn a ligament in his ankle.
There are more worries for the Bulls with wings Divan Rossouw and Jade Stighling who will also miss their upcoming home fixture against the New South Wales Waratahs, after they left the field with concussion at the weekend.
Better news for Coach Pote Human is that centre Burger Odendaal will be eligible after being cleared by a specialist after sustaining an eye injury against the Stormers.
The Bulls are second in the South Africa Conference, two points behind the Sharks but with a game in hand.
