Jockey Brad Rawiller is having his troublesome neck examined at hospital in Ballarat after a barrier incident on Wednesday.
Rawiller only returned to riding two months ago after being sidelined for nearly six months with two broken vertebrae in his neck.
The 40-year-old rider was attended to by ambulance on course after the late scratching of his mount Havadash before the fifth race.
Rawiller asked stewards if he could be permitted to drive home however stewards ordered he instead be taken for further examination at Ballarat hospital.
Rawiller has been in great form of late and earlier this month strung together six winners over a five day period.
He has important rides booked for Eagle Farm this Saturday headlined by Redouble in the G1 Kingsford-Smith Cup (1300m) and Leonardo Da Hinchi in the G3 Fred Best Classic (1400m).
