Has an AFL game ever ended 48-48?
Exactly once. On July 2, 1927, Essendon and Fitzroy drew 48-48, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 48-48 in league history.
That makes 48-48 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 49-48 has happened 2 times and 48-49 has happened never.
