One flag-marshal admitted for observation and released this morning, Chaz Mostert (driver of car #6) had a rod inserted into his femur to hold the bones aligned and a plate in his left wrist .. will be released in a few days but he will be out for the rest of the season.
There was a second incident in one of the support categories ("Aussie" racing cars which are 5/8 sized replica's of a SuperCar with a 1300cc motorcycle engine which was more serious .. driver hospitalised with punctured lung and multiple rib-fractures ... that guy was very lucky.
