Ireland prop Jeremy Loughman should not have been allowed to return to the field after suffering concussion symptoms against the Maori All Blacks, New Zealand Rugby (NZR) has concluded.
A review into the incident found the correct protocols were not followed due to a communication error.
Munster loosehead Loughman was filmed falling backwards as he attempted to return to his feet following a collision in the second minute of Wednesday’s 32-17 defeat in Hamilton.
