Springbok and Lions captain Warren Whiteley will miss the rest of his franchise's Super Rugby campaign and could also possibly miss South Africa's Rugby Championship opener against Argentina in Port Elizabeth on August 19.
Whiteley missed Saturday's third Test against France with a groin injury and Lions team doctor Rob Collins said the number eight underwent a scan that showed he had torn ligament in his pelvis.
No surgery is going to be required.
Springbok coach Allister Coetzee had hinted that Whiteley was being managed throughout the international window but aggravated the injury in the week leading up to the 35-12 blanking of the French at Ellis Park.
