Has an AFL game ever ended 47-34?
Exactly once. On April 27, 1912, Sydney beat Fitzroy 47-34, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 47-34 in league history.
That makes 47-34 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 48-34 has happened never and 47-35 has happened never.
