FIFA's match commissioner for England's clash with Scotland holds the key as to whether or not disciplinary action is taken for players wearing poppies.
The world governing body has reiterated they have not outright banned the two nations wearing a black armband with the poppy symbol for the match at Wembley on Friday night.
FIFA claim reports to the contrary are a "distortion of the facts", after general secretary Fatma Samoura restated Law Four of the game - the banning of "political, religious or personal slogans, statements or images" - during a visit to London last week.
Both the FA and SFA insist their teams will wear the remembrance poppy in honour of Armistice Day, as they have done for decades without reprimand.
And FA chief executive Martin Glenn has confirmed that legal guidance has built a "rock solid" case in their favour.
Whether the two countries should be investigated or not is a matter of interpretation for the match commissioner, who must decide whether or not to include the action in his or her report.
Any case would then go to the FIFA disciplinary committee, with potential sanctions including a fine or points deduction. Should a decision go against them, the FA and SFA could appeal to FIFA's Appeals Committee and the Court of Arbitration for Sport.
A fine could fetch as much as £30,000, but FA chief Glenn said on Thursday: "If FIFA fine us, we'll contest.
"I'm confident our legal position is right and our moral position is right. Our case is absolutely rock solid."
