Al Ittihad played Al Faisaly in the King's Cup final at Jeddah's King Abdullah Sports City on Saturday, winning in extra-time in a game refereed by former Premier League official Mark Clattenburg.
Al-Mirdasi has confessed to his illegal bid to fix the match in favor of Al-Ittihad.
SAFF has already banned Al Mirdasi for life after he asked for bribe to influence the outcome of a match.
It now emerges that he confessed to offering to fix Saturday's King's Cup final on behalf of Al Ittihad club, according to the Saudi FA which added that it had requested Federation Internationale de Football Association to confirm the lifetime global ban as well as removing him from the World Cup list.
The committee recommended that Saudi Arabia officially request Federation Internationale de Football Association to remove Mirdasi from the list of referees participating in the 2018 World Cup and suspend him for life. Al-Senaie handed over Al Mirdasi's WhatsApp messages to Saudi Arabian Football Federation, which has asked FIFA to extend the ban world-wide. "Following the investigations, the Saudi Federation received the report of the competent authorities, which proved the charge against the referee under his personal confession of the request for bribery".
However, world soccer's governing body has requested more information before taking actions against Al Mirdasi, who officiated last year's third spot playoffs between Portugal and Mexico at the Confederations Cup and was one of five Arab referees designated for this year's World Cup. He was also a referee at the 2016 Rio de Janeiro Olympics.
