The National Football League will have to justify its hypocritical anti-gambling stance in court.

On Monday, a Texas-based company named The Fan Expo LLC sued the NFL in US District Court in Dallas County. Fan Expo is seeking over $1m in damages related to last month’s abrupt cancellation of the National Fantasy Football Convention (NFFC).

The three-day convention, which was to feature Dallas Cowboys quarterback Tony Romo and a host of other NFL stars, was scrapped one month before it was set to kick off after the NFL ‘reminded’ the NFL Players Association of its longstanding policy of not associating the NFL brand with gambling.

The NFFC was scheduled to take place at the Sands Expo in Las Vegas, a non-gaming appendage to Las Vegas Sands’ Venetian Resort Hotel Casino. But the NFL insisted that this proximity contravened its policy of preventing its players from engaging in “promotional activities or other appearances at or in connection with events that are held at or sponsored by casinos.”
