First choice hooker Ford and lock Gray, who forms an effective partnership with older brother Richie, have been cited for a lifting tackle during Scotland's thrilling 36-33 win over Samoa on Saturday.
Their hearing will take place in London on Tuesday morning and will be heard by English lawyer Christopher Quinlan.
Australia will have breathed a sigh of relief as star No.8 David Pocock escaped a citing for an incident during their epic 15-6 win over Wales on Saturday.
The 27-year-old Zimbabwe-born back row forward received a post-match warning, the equivalent of a yellow card. He could be called to a hearing after three warnings or yellow cards.
"Pocock is therefore free to play in Australia’s quarterfinal against Scotland," said a Rugby World statement.
