Uefa president Michel Platini will find out this week whether his 90-day Fifa ban will be lifted for now.
Platini, 60, was suspended with Fifa president Sepp Blatter in October while corruption claims are investigated. They deny any wrongdoing.
His lawyers will attend a preliminary hearing with the Court of Arbitration for Sport (Cas) on Tuesday.
Cas said a decision over Platini’s ban appeal will be made by Friday, 11 December.
The former France midfielder wants to run for the Fifa leadership but is banned from any football-related activity.
Platini and Blatter have been suspended over allegations that a “disloyal payment” of £1.3m was made to Platini in 2011 for work he carried out for Fifa between 1998 and 2002.
If Platini wins his appeal, the Fifa electoral committee has said it would review his case, but there is no guarantee he would be able to stand in the election to replace Blatter.
Blatter has announced he will stand down, and Fifa’s next president will be chosen at a special congress on 26 February 2016.
