The AFC said in a statement on Friday that it supported the FIFA Security probe, promising to "assist FIFA and cooperate closely with the world football governing body."
The statement came one day after the security department said it “will conduct a routine examination of this game and its result."
Bahrain’s Wednesday win raised suspicion because the squad needed a huge turnaround to have any chance of reaching the fourth round of regional 2014 World Cup qualifiers.
Bahrain had to beat Indonesia and needed Qatar to lose to Iran and also needed to create a nine-goal differential on Qatar.
The 10-goal rout almost sent them through, but Qatar advanced after an 86th-minute goal gave them a 2-2 draw against Iran and the point they needed to clinch the second place in Group E.
Indonesia, already eliminated, fielded a vastly inexperienced side of mostly uncapped under-23 players. Lebanese referee, Andre El Hadded, also sent off Indonesia’s goalkeeper, Samsidar, after just two minutes.
FIFA's records show that the two sides had met six times before with two wins apiece and two draws. Bahrain had not previously won by any more than two goals.
