Has an AFL game ever ended 50-38?
Exactly once. On June 26, 1915, Fitzroy beat Carlton 50-38, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 50-38 in league history.
That makes 50-38 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 51-38 has happened never and 50-39 has happened 1 times.
