Adelaide’s Jordan Elsey was sent off for a second bookable offence just after the hour, with Sydney 3-0 up.
Veart was furious about the standard of refereeing from South Australian Elder, and he made his views well known in the post-match press conference.
“You’d think that in a game of such importance we would have got one of the top referees,” Veart said.
“But we get a South Australian referee that shows everyone he doesn’t want to be South Australian and goes harder against Adelaide United.
“He did it last time when we had him and he did it again.”
Veart has an opportunity to provide a submission to Football Australia by 5pm on Monday.
Fourth-placed Adelaide (38 points) will be back in action on Thursday when they host the eighth-placed Western Sydney Wanderers (34 points) in the final match of their regular season.
