World Cup-bound referee Fahad Al Mirdasi, one of Asian football's most experienced officials, has been placed under investigation in Saudi Arabia.
The Saudi Football Federation removed Al Mirdasi from overseeing the King's Cup final on Saturday after referring him to administrative investigators.
The federation did not specify the nature of the investigation into the 32-year-old.
FIFA said the matter "is with the Saudi Arabian Football Federation," declining to offer further comment on Al Mirdasi's status at the World Cup, which starts next month.
The official was selected for last year's Confederations Cup, which served as the World Cup warm-up tournament in Russia.
He oversaw the third-place game between Mexico and Portugal in which two penalties were awarded, two players sent off in extra time and Mexico coach Juan Carlos Osorio also dismissed.
Al Mirdasi was also a referee at the 2016 Rio de Janeiro Olympics.
