Algerian referee Mustapha Ghorbal became the centre of controversy after Haiti's World Cup match against Scotland, with Haitian supporters strongly objecting to a number of decisions during the game.
According to reports circulating after the match, Haiti fans called on FIFA to review the disputed incidents and investigate the officiating performance in the contest.
No official FIFA response had been issued by the time of writing, but the uproar has added a fresh refereeing subplot to the group's early drama.
