North Adelaide will face Norwood in the 2018 SANFL Grand Final, despite fielding 19 players for over four minutes during their five-point win over Woodville-West Torrens on Sunday.

The Roosters scored eight points during the time they had an extra man on the field, and were found to be "grossly negligent" during their preliminary final win, according to the judiciary.

The club were fined the maximum amount of $10,000, and were also docked four premiership points for next season.

The Hon. Michael David QC oversaw the hearing, and said the most appropriate penalty would be a replay, although he didn't have the power to make that ruling.

"To me, a rematch would seem to be the most appropriate penalty, but I have no power to do so," he said.

"I'm of the view that as this was not deliberate, a reversal of the result is too savage a penalty and the matter should be dealt with by matter of fine and loss of premiership points for next year.

"Sadly, this is of little consolation to the Woodville-West Torrens Football Club.

"I fine the North Adelaide Football Club the maximum amount of $10,000 because this was grossly negligent and by way of deterrents, and I dock them the loss of four premiership points for next season."

David believes the fact the Woodville-West Torrens captain didn't call for a head count didn't go against the club, suggesting he did not expect them to act on such an outdated rule.
