AEK Athens have been deducted three points by the Greek Football Federation following a pitch invasion by their fans earlier this month.
The disciplinary committee of the federation also ordered second-division side AEK to play two matches behind closed doors, while the club were also fined 17,000 euros.
The incident happened during the Greek Cup quarter-final tie between AEK and Olympiakos at the Athens Olympic Stadium with just one minute remaining in the game on March 12.
Approximately 25 AEK supporters ran onto the pitch, throwing objects and chasing Olympiakos players following an 89th-minute goal by midfielder Franco Jara which gave the visitors a 1-0 lead.
The Olympiakos players immediately headed to the changing rooms and they were soon followed by match officials and AEK players.
Around 30 minutes later, officials announced that the game would not resume and Olympiakos would automatically progress to the semi-finals, being awarded a 3-0 victory.
The violence led deputy sports minister Stavros Kontonis to ban spectators from Super League matches.AEK are already assured of promotion to the Greek Super League with a 16-point advantage over second-place Panachaiki.
