FIFA vice-president Michel Platini will attend a Court of Arbitration for Sport (CAS) hearing on Tuesday for an appeal against a 90-day suspension, his entourage said.
The appeal is part of a new campaign by Platini to get back into the election for a new FIFA leader on February 26.
The 60-year-old Frenchman will go to the CAS tribunal in Lausanne with his lawyers on Tuesday, an aide told AFP.
CAS has promised a decision on his appeal by Friday "at the latest."
FIFA`s ethics committee in October suspended Platini, head of European football governing body UEFA and a FIFA vice president, from all football activities for 90 days after he was linked to a criminal probe by Swiss prosecutors.
According to Platini`s lawyers, FIFA`s ethics watchdog wants the French football legend banned for life.
Platini has gone to CAS in a bid to get the suspension temporarily lifted. The Frenchman and FIFA president Sepp Blatter will appear before a FIFA appeal committee on December 16-18 for the main challenge against their 90 day suspensions.
Blatter is the target of a criminal mismanagement investigation by Swiss prosecutors. Platini has been questioned over a two million Swiss france($2 million) payment he received from FIFA in 2011 for work done a decade earlier.
Both men deny any wrongdoing.
