Has an AFL game ever ended 47-26?
Exactly once. On August 9, 1913, Geelong beat Melbourne 47-26, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 47-26 in league history.
That makes 47-26 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 48-26 has happened never and 47-27 has happened never.
