Has an AFL game ever ended 50-39?
Exactly once. On May 22, 1897, Melbourne beat Fitzroy 50-39, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 50-39 in league history.
That makes 50-39 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 51-39 has happened 1 times and 50-40 has happened never.
