PAOK Salonika, the Greek club banned from Europe in 1992 because of crowd violence, will have at least three points deducted and their ground closed for up to 10 matches after fans rioted at a home match on Monday.
The Greek football federation said that the points deduction will be the minimum punishment handed out by a federation tribunal in the next two days.
The violence was sparked by a pitch invasion by some 300 hooligans and ended with 30 people injured - including the referee - and seven arrests.
Although the game was abandoned two minutes from time with PAOK trailing 3-1, the result will stand.
The Salonika club were banned from European competition for two years in 1992 after fans rioted during a Uefa Cup match against Paris St- Germain. The ban was later cut to one year.
