UEFA president Michel Platini appealed on Friday at the Court of Arbitration for Sport (CAS) against a six-year ban from football.
Platini was banned by the ruling body FIFA in connection with a disloyal payment of 2 million dollars he received from then FIFA president Joseph Blatter in 2011 for FIFA work done as a FIFA presidential adviser a decade earlier.
Blatter, who was a witness at the hearing, is also appealing the FIFA ban but a date for his hearing is yet to be set.
CAS secretary general Matthieu Reeb was quoted as saying that a ruling on Platini's appeal could come by May 9.
A UEFA congress is scheduled for Tuesday in Budapest, and if Platini remains suspended a timetable for a presidential election could be looked into in Hungary. The UEFA executive committee meets Monday.
Platini hopes to be cleared to oversee the Euro 2016 tournament in his native France in June and July in his function as UEFA boss.
