The Steelers won their game Sunday against the San Diego Chargers, in the first ever 11-to-10 final in NFL history.
But here is where it gets a little complicated.
A blown call by the officials on the final play took away a Steelers touchdown on a Chargers' fumble.
While the mistake didn't alter the game's outcome, it had a big impact on the point spread.
The Steelers still won, but not by enough for bettors to also win.
John Avello, of the Wynn resort in Las Vegas, says a lot of people weren't very happy.
He figures $10 million was wagered on the game legally in Nevada.
The NFL says it's taking a closer look at how instant replay is used to prevent future mistakes.
