Greek side Olympiakos Volos were handed a three-season ban from continental competition on Thursday, meaning they have been removed from this season's Europa League.
The Hellenic Football Federation (EPO) issued points deductions to Volos (10) and another club, Kavala (8), before the start of the Super League season for their role in a match-fixing scandal.
"Olympiakos Volos FC have been excluded from this season's Europa League and given a further three-year ban from UEFA competition, deferred for a probationary period of five seasons, after breaching Article 5 of the UEFA Disciplinary Regulations," UEFA said in a media statement on Thursday.
"The decision was taken by the UEFA Control and Disciplinary Body. The Greek club have until midnight on Monday to submit an appeal under Article 49 of the UEFA Disciplinary Regulations.
"The UEFA administration will decide which club will replace Olympiakos Volos in the UEFA Europa League, where they were scheduled to face Paris Saint-Germain in the play-offs on August 18 and August 25."
Club lawyer Michael Mitzikos said: "We will appeal first to UEFA's appeal's body and will also consider measures with the CAS (Court of Arbitration for Sport)."
