LAUSANNE, Switzerland -- Sepp Blatter will go to sport's highest court on Aug. 25 to challenge his six-year ban from football for approving a $2 million FIFA payment to Michel Platini.

The Court of Arbitration for Sport set the former FIFA president's appeal hearing date on Friday to be held at its headquarters in Lausanne.

Blatter's day in court will come more than three months after CAS imposed a four-year ban on Platini for conflict of interest.

A different CAS panel in Platini's case said it was ''not convinced by the legitimacy'' of the payment to Platini. The money was uncontracted extra salary for working as Blatter's presidential adviser from 1999-2002.

Both were banned for eight years by FIFA's ethics committee last December.

FIFA's appeal committee cut two years off their sanctions.
