South Sydney coach Michael Maguire says play in their NRL clash with Melbourne shouldn't have continued with his winger Dylan Farrell knocked out on the side of the field.
He said the game had a duty of care to put players first and he will seek clarification this week from the NRL as to why the referees didn't stop the game at AAMI Park.
It continued for several minutes late in the second half while Farrell lay prone in-goal before being attended to.
He was stretchered from the field with his neck in a brace.
Maguire said the young winger was initially in a "bad way" but had pulled up reasonably well post match.
