Sion goalkeeper Essam Al-Hadari has been banned for four months after violating his contract with Ahli, the Cairo giants claimed on Friday. "FIFA's Dispute Resolution Chamber decided to ban Al-Hadari for four months and fine him €900,000," Ahli said in a statement on their website. "Al-Hadari will start serving the ban in August. Sion will also be prohibited from signing any players for two transfer windows." The Egypt guardian has been at loggerheads with Ahli officials and fans alike since joining Swiss side Sion without the club's approval in February 2008. The Red Devils took the case to world governing body FIFA as they sought to gain compensation. Al-Hadari was confident that he would not be punished though. "Ahli officials are saying nonsense. They spread rumors about alleged suspension and wait for any chance to slaughter me," he said last week. If the 36-year-old serves a four-month suspension, he will miss Egypt's World Cup qualifiers against Algeria, Rwanda and Zambia. However, he will be available for Egypt's Confederations Cup campaign in June.
