The Bulls will be without Springbok centre Jan Serfontein for the next two weeks of their Super Rugby campaign.
The midfielder sustained a knee injury in their 20-19 win over the Sharks last weekend and has been ruled out for at least a fortnight, team doctor Org Strauss confirmed via the Pretoria-based franchise's official website.
Serfontein is the only casualty from the clash which moved the Bulls to the top of the standings.
Jacques Potgieter (hand), Akona Ndungane (hamstring), MornÃ© Mellett (neck), Wilhelm Steenkamp (neck), Ulrich Beyers (flu) and Hencus van Wyk (neck) will all miss training on Monday due to minor ailments.
Cornell Hess (knee), Lionel Mapoe (shoulder), Arno Botha (knee), Pierre Spies (bicep) and Louis FouchÃ© are all long-term injuries
