The visiting goalkeeper was sent off after just two minutes, and Bahrain's win on Wednesday has raised suspicion because it needed to make up a nine-goal difference on Qatar in the group standings to have a chance of reaching the next round.

　　Bahrain also needed Qatar to lose its last match, but Qatar tied with Iran 2-2 to instead reach the next stage of the Asian qualifying tournament.

　　"Given the unusual outcome in relation to the results-expectation and head-to-head history, and in the interests of maintaining unequivocal confidence in our game, FIFA Security will conduct a routine examination of this game and its result," said a FIFA statement.

　　"The important thing is that if there are suspicions you have to investigate it," FIFA Vice President Prince Ali said during a trip to London. "It might just be a coincidence, however there might be something behind it."
