Prodrive Racing (Australia) driver Chaz Mostert will undergo more surgery tomorrow to repair ligament damage behind his left knee cap.
The damage was discovered during post-surgery scans earlier today and corrective surgery is required to aid his recovery.
Mostert underwent surgery on Saturday following a large crash during last Friday's qualifying for the Supercheap Auto Bathurst 1000. His initial surgery repaired a fractured left leg and wrist.
"The knee cap kind of ripped itself in the crash -I might be at the Gold Coast 600, just depends," Mostert told fans this evening on Periscope.
"The knee is going to have to have another op tomorrow which is a pretty hard thing because I've already been here for one op - getting this fixed in the short term and getting back on the road to healing is probably the biggest thing."
Mostert will remain in hospital for at least the next few days while he recovers from surgery before being choppered home to the Gold Coast in Paul Morris's helicopter.
Speaking to his fans, Mostert didn't give any of the team's plans away but backed his young co-driver Cam Waters to drive car #6 for the remainder of the season.
"I think they've organised drivers - not too sure if I'm allowed to say anything yet but I think they've got a good line-up for car #6 for the Gold Coast weekend, so hopefully the car will be firing on all cylinders," Mostert said.
"I'm not too sure [who will drive for the rest of the year] but I'm hoping Cam so he can get some good miles under his belt and that will obviously be good for the team's Championship as well."
