Has an AFL game ever ended 89-43?
Exactly once. On June 29, 1991, Footscray beat Essendon 89-43, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 89-43 in league history.
That makes 89-43 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 90-43 has happened never and 89-44 has happened 3 times.
