"Jon Petrie felt a crack in his neck and he is off to the Royal North Shore hospital," said Scotland coach Matt Williams.
"He is walking and it is just a precaution but you don't muck around with neck injuries."
Although the Scotland camp were disappointed, centre Graeme Morrison produced another impressive display up against former Australia international Nathan Grey.
"Graeme Morrison was absolutely outstanding, the best player on the field," continued Williams.
"He made the gain line and broke it every single time."
