The Bulls have suffered a big blow ahead of their Super Rugby match against the Sharks at Loftus Versfeld as captain Flip van der Merwe has been ruled out due to injury.
The Bulls have replaced Van der Merwe with Paul Willemse in the starting line up and the captaincy will be taken over by Victor Matfield for the first time since 2011.
Grant Hattingh, who was due to play for the Blue Bulls in the Vodacom Cup clash against the Golden Lions on Saturday, has been promoted to the bench for the Bulls.
