Australian driver Will Power remained in hospital on Wednesday in the wake of his IndyCar practice crash with French driver Nelson Philippe on Saturday.

The 28-year-old Queenslander has been fitted with a back brace and is expected to be transported to Indianapolis within the next two days for further examination by IndyCar Series orthopaedic specialist Terry Trammell.

The crash occurred when Philippe’s stalled car was hit by Power’s vehicle as the Australian driver rounded a blind corner at Infineon Raceway in Sonoma, California.

Power suffered a concussion and compression fractures of two vertebrae in his lower back.

He remains at Santa Rosa Memorial Hospital but is expected to make a full recovery, the Indianapolis Star reported.

Philippe has been released from hospital and has returned to his home in Florida after surgery to repair a serious fracture of his left foot.
