Has an AFL game ever ended 52-23?
Exactly once. On July 11, 1931, Geelong beat Footscray 52-23, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 52-23 in league history.
That makes 52-23 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 53-23 has happened 1 times and 52-24 has happened never.
