The Swiss club confirmed on their official website that they will be appealing FIFA's decision to suspend the Egyptian guardian.

Al-Hadari joined Sion in February 2008 without the consent of his former club Ahli.

He was suspended as a result and Sion were handed a fine of 900,000 Euros in addition to banning the club from signing any players for two transfer windows.

If Al-Hadari and Sion lose the appeal, the goalie will be required to serve the suspension starting next season.

The 36-year-old is currently with the Egypt squad, which will face Algeria and play in the Confederations Cup.
