Has an AFL game ever ended 48-29?
Exactly once. On May 21, 1955, Geelong beat St Kilda 48-29, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 48-29 in league history.
That makes 48-29 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 49-29 has happened 1 times and 48-30 has happened never.
