Southern Kings Hooker, Hannes Franklin, and lock Darron Nell both suffered knee injuries during training this week.
Director of Rugby, Alan Solomons says it looks as if Franklin will be out for 6 to 12 weeks after tearing the medial collateral ligament in his left knee.
Nell, who is also part of the Southern Kings 40-man squad, suffered a freek knee injury when he collided with a partially exposed sprinkler head.
He suffered soft tissue injury and will be out for about three weeks.
