Has an AFL game ever ended 50-24?
Exactly once. On May 25, 1901, Essendon beat Melbourne 50-24, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 50-24 in league history.
That makes 50-24 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 51-24 has happened never and 50-25 has happened never.
