PAOK and Xanthi have been docked points by the sports judge examining the case of their alleged joint ownership, altering significantly the Super League table just before the playoffs and playouts kick off.
PAOK is now 14 points behind leader Olympiakos as it was docked seven points on Thursday, to stay in second but just one point ahead of AEK.
Champion PAOK unexpectedly dropped two points on Sunday at the club it is alleged to share the same owner, Xanthi, and finished the regular season of the Super League seven points behind leader Olympiakos.
The Reds will therefore need eight wins in the 10 games of the playoffs to clinch the title. The playoffs begin on March 7 and the draw for the schedule will take place on March 3.
Prime Minister Kyriakos Mitsotakis said Thursday that the presidents of international soccer's governing bodies, FIFA and UEFA, will be invited to Greece to help draft a "memorandum" to overhaul the country's troubled Super League.
Speaking in Parliament, Mitsotakis said that the government would not hesitate to suspend the country's championship if the problems persisted.
Parliament on Wednesday backed a controversial legal amendment that will prevent northern Greek soccer clubs PAOK and Xanthi from being relegated due to alleged infringement of ownership rules.
The amendment passed by 156 votes to 90. Fifty-four deputies abstained.
Antonis Samaras, a former prime minister, and Giorgos Vagonias from New Democracy were absent from the vote.
Fearing reactions in northern Greece that would divide the country between north and south, the government on Tuesday announced an amendment that would ensure that northern clubs PAOK Thessaloniki and Xanthi are not relegated due to a breach of Super League rules which forbids two clubs from having common ownership.
