Australian GP: Valtteri Bottas may not race after back injury
Williams driver Valtteri Bottas's participation in the Australian Grand Prix is in doubt after he suffered a back problem during qualifying.
The Finn, who qualified sixth, said he first felt the problem during the second knock-out part of qualifying.
Bottas then ran wide over a kerb in final qualifying, exacerbating his discomfort.
Bottas said: "The team and I felt it sensible to get it checked at the local hospital and we await their diagnosis."
