The Pittsburgh Steelers walked off the field Sunday just happy they had won.

The same can't be said for an untold amount of bettors.

Winners turned into losers and losers ended up winning at the sportsbook when a game that should have ended up 17-10 or 18-10 instead went into the record books as an 11-10 final. Though the score made no difference in the win and loss column, it did in the wallets on the Las Vegas Strip.

"Anyone who had a bet on the Pittsburgh side and thought they had won weren't too happy," said John Avello, director of the race and sports book at city's Wynn resort.

A mistake by the officials on the final play of the game between the Steelers and San Diego Chargers didn't alter the outcome.

San Diego tried to lateral the ball amongst themselves on the game's final play in a desperate attempt to win. Pittsburgh's Troy Polamulu scooped an errant Charger throw and ran into the end zone for an apparent 17-10 lead before the extra point.

The Steelers were favored by 4 points.

After much delay, the officials decreed that one of San Diego's laterals went forward, which is against the rules. But after the game referee Scott Green said the officials realized that all of the laterals were legal, and therefore, Pittsburgh's touchdown should have counted.

Avello said there might have been $10 million bet on the game in Nevada, and many times more than that in illegal bets around the country and in offshore Internet betting sites. There was more money bet on Pittsburgh, he said, especially in parlay bets.

Though the officials later said they made a mistake in calling back the touchdown, the official score remains 11-10, and even if the NFL changes it, Nevada sports books paid off on the final score from Sunday.

While it's highly unlikely, Pittsburgh could conceivably be affected at season's end. Points scored can be used to determine playoff tiebreakers.

Adding to the weirdness, there had been no 11-10 game in 12,837 NFL previous games.
