Apprentice jockey Anthony Boyd is in a Melbourne hospital after a track work fall at Ballarat.

Boyd was placed in an induced coma on Thursday morning and airlifted to the Alfred Hospital amid concerns he had suffered a serious head injury.

But Victorian Jockeys Association chief executive Matt Hyland provided an encouraging update on Thursday afternoon.

"The latest update is initial scans have cleared him of any significant damage to his head, which is where the concern was," Hyland said.

"He was placed in an induced coma to be airlifted down (to Melbourne).

"At this point there is no need for surgery.

"He's still heavily sedated and they'll gradually wean the sedation off him and hopefully it all goes to plan."

Boyd remains in ICU for further observation.
