Concacaf (North and Central America and the Caribbean) and the AFC (Asia) also - in their own ways - have offered withering assessments of how Fifa is being run under Infantino.
"This issue extends far beyond a single proposal," said the AFC. "Rather, it has exposed fundamental weaknesses in Fifa's consultation and decision-making processes that must now be addressed."
Sources say, in addition to rejecting Infantino's plan, the vast majority of the Concacaf members are either losing faith in the Fifa president's ability to govern the game, or have lost it altogether.
On top of that, Carlos Cordeiro, special adviser to Infantino and appointed by Trump as senior adviser to the White House Task Force on the 2026 World Cup, has resigned.
Fifa's chief operating officer Kevin Lamour said in a statement to Associated Press that Fifa's own administration was "deceived" about the project.
BBC Sport has approached Fifa for comment.
It feels as though the walls are closing in on Infantino.
But if this is the beginning of the end of his tenure, who takes over?
