In a tough blow for the midfielder, Antonis was driving to the airport on Sunday evening to travel to Japan when the accident occurred, with the 20-year-old taken to hospital having complained of head and neck pain.
Scans at the hospital cleared Antonis of any major injury but the youngster has still been withdrawn from the Socceroos squad to face Japan on November 18 after a consultation between Sydney medical staff and Australian coach Ange Postecoglou.
The Socceroos’ boss has named Swiss-based midfielder Oliver Bozanic as Antonis’ replacement in the squad.
