Melbourne Victory face the prospect of a points deduction and playing games behind closed doors after Football Australia officially slapped the A-Leagues club with a show cause notice for their fans' violent derby pitch invasion.
Saturday night's A-League Men match was abandoned after fans from the Victory active area stormed the AAMI Park pitch.
Melbourne City goalkeeper Tom Glover was hit by a metal bucket wielded by a pitch invader and referee Alex King was also injured, while a Network 10 cameraman was earlier hit by a flare.
