A lawsuit for more than $1 million in damages has been filed against the NFL in regards to Tony Romo's cancelled National Fantasy Football Convention from early July.

Fan Expo LLC, the company behind the NFFC, sued the league on Monday accusing the NFL of illegally interfering with the NFFC that was supposed to take place on July 10

The event, headlined by the Dallas Cowboys quarterback, was supposed to involve over 60 NFL players including the likes of Dez Bryant, Jason Witten, DeMarco Murray, Rob Gronkowski, Julio Jones, and many more.

Fans were going to get the ultimate fantasy football and NFL experience at the Sands Expo Center in Las Vegas — a property owned by a casino but encompassed no on-site gambling. The NFL was not pleased with this.

In June, a Fox Sports news report revealed that the league informed the NFLPA that the three-day Las Vegas convention violated the NFL rules on events held on casino properties.

“Players and NFL personnel may not participate in the promotional activities or other appearances at or in connection with events that are held at or sponsored by casinos,” a league spokesperson said in an email to Fox Sports.

As ESPN's Darren Rovell points out, "The NFL's gambling policy states that the league does not allow participating in any appearances that are held or sponsored by a gambling-related establishment. But Fan Expo LLC argues that its three-day event wasn't in violation of that policy."

The suit also argues that the NFL has a complicated gambling policy when looking at what other teams have done. The New Orleans Saints held their training camp last year at a resort with a 103,000 square foot casino. The Detroit Lions were recently came across a sponsorship with the MGM Grand Detroit.

The Fan Expo has no further statement on the lawsuit and the league is currently unaware of the legal action.
