The Austrian national team has expressed concern over the condition of defender Stefan Posch, following the 3:1 victory over Jordan in the opening match.
The 29-year-old risks missing the World Cup.
He was injured in the face in the final minutes of the match.
Coach Ralf Rangnick stressed after the match that if the jaw injury is present, he will miss the entire tournament.
In addition to Posch, captain David Alaba also suffered an injury against Jordan.
The center back was replaced by Kevin Danso in the 59th minute.
