NSW country jockey Michael Hackett remains in an induced coma in Sydney's Liverpool Hospital after a fall at the Tomingley Cup picnic meeting.

Hackett was one of three riders to fall in the second race at the western NSW meeting on Saturday.

He was airlifted to Sydney and the NSW Jockeys Association said on Monday he remained stable in an induced coma with family by his side.

The NSW JA says Ricky Blewitt, who was taken to Westmead Hospital, has stable in-displaced thoracic spine fractures requiring rest for six weeks.

He also has a scapula fracture that will be treated with a sling and a rib fracture that requires rest and conservative management.

Michael Gray will undergo an MRI and if it is clear he will soon be discharged from Dubbo Hospital.

He has a fractured clavicle which Racing NSW's Dr David Duckworth will operate on on Wednesday.

He also has a wrist fracture that will be treated in a splint and a thoracic spine fracture that requires rest.
