The only other time a winner was disqualified in Kentucky Derby history was not for an on-the-track violation.

In 1968, Dancer’s Image, the first-place finisher, tested positive for a prohibited medication, and Kentucky state racing officials ordered the purse money to be redistributed, according to the AP. Forward Pass got the winner’s share. A subsequent court challenge upheld the stewards’ decision.

The shifting victor of course changed a lot of bettors' futures as well.

A record $250.9 million was wagered on the race across all platforms -- online and at the track -- an increase of 11% from last year, according to the track.
