Justin Houston's TD for Chiefs had big ramifications for bettors

LAS VEGAS -- The last two NFL weeks have gone to the books. On Monday night, the betting public got a little bit of revenge.

Kansas City Chiefs linebacker Justin Houston returned a fumble 13 yards for a touchdown as time expired in the Chiefs' 29-20 win.

Kansas City was a 7-point favorite at most sportsbooks and attracted the bulk of the betting action.

In a back-and-forth game, the Chiefs took a 23-20 lead with 4 seconds left on a 43-yard field goal by Harrison Butker.

After a touchback on the ensuing kickoff, Washington took over on its own 25-yard line. Quarterback Kirk Cousins completed a short pass to Jamison Crowder, who threw the ball back to Cousins in an attempt to start a multi-lateral play. After a scramble, the ball ended up the ground. Houston scooped it up and raced into the end zone, prompting ESPN play-by-play man Sean McDonough to say, "This might be meaningful to some."

It certainly was.

The last-play defensive touchdown caused an approximately $350,000 swing against the house at Las Vegas sportsbook operator CG Technology, according to vice president of risk Jason Simbal, who added that $100,000 of that loss came from one big bet on the Chiefs -7.

Houston's touchdown not only covered the spread, but also pushed the game over the total, which was listed around 48.5.

At William Hill's Nevada sportsbooks, 67 percent of the money bet on the game was on the Chiefs.

"A very significant final play," Michael Grodsky, vice president of marketing for William Hill, told ESPN in an email. "For us, it was a mid-six-figure swing in favor of the customers."
